Mouse Reviews

This is a great little mouse. I bought it while traveling because I had forgotten to bring one of my own. The mouse itself is small (about 3.5" in diameter) which is definitely useful on a plane or other confined space. I've even used it on the wrist rest of my laptop with no problem.

It has an 800 dpi resolution (twice of most mice) so that it moves twice as far on the screen with the same movement on a surface as most mice do, which also helps in small confines. It is also an optical mouse so the movement on any surface and on the screen is very smooth, and the scroll wheel is a nice touch (and the scroll wheel GLOWS BLUE, extra special).

The retractable cord is also nice. It unwinds and easily (it retracts with a short tug on either side of the cable) and you can unwind it to any length up to about 32".

The reason it didn't get a better rating is because it is so small. I have medium-large hands and it is difficult to use sometimes, especially with the TINY buttons. Other micro mice seem to have larger buttons and are shaped more ergonomically.

This is a great mouse for traveling; it packs up small and works nicely. If you have larger hands, you may want to avoid it. Will I keep using it because of the cool blue scroll wheel? Absolutely... until my hand cramps up.

This optical mouse works at the moment you plug it in, didn't need to install the driver. Great for laptop computer users, small enough to carry it wherever you go, no need to struggle with wires, the retractable cord is what you're looking for. Nice blue glowing of the scroll button, it was a gift from my girlfriend and I'm so glad she gave it to me, great help and it's ready to use. And an amazing thing, its price, it's worth it.

I bought it as a gift for my brother. Its small fits easily in his laptop case and he can use any where he wants to.

I own the Logitech Cordless Navigator Duo since about 6 month now.

First the good news:
The mouse is great, it's ergonomic, has two buttons plus the wheel which incorporates a third button. The handling of the mouse is very nice and precise, it works on almost any surface.

The bad news:
I am running a variety of operating systems: Windows 2000, DOS, Gentoo Linux and BeOS. The keyboard does ONLY work as it is supposed to with Windows and DOS. All the other systems are a nightmare with this keyboard. The so-called "ghost letters" appear constantly. This means that when I am typing in any software, letters appear which I did not type, on it's own. In my case it's the "q" letter. On other occasions it's just a space. This mostly happens when I use the backspace key--the keyboard inserts a space on it's own.
This really is a nightmare if you regulary write emails etc., the only work-around is to use the delete-key instead of the backspace key. On Linux it also seems to help to disable the F-keys. However, then you won't be able to use the F-Keys.

I know I am not alone with this problem. If you google for the phrase "unknown e1 escape sequence" in Google Groups, you will notice that several people have the same problem and noone ever found a solution.

Afterall I really urge everybody who wants to use other systems than Windows not to consider this keyboard, it will drive you crazy.

I recently tried a Microsoft wireless combo to replace a wrecked keyboard on my HP PC. I exchanged the MS for the Logitech and am much happier. The big difference is the layout of the Function keys and keys over the arrow keys. The MS board has the F1-F12 keys in four groups of three; the Logitech has them in three groups of four, like every other keyboard I use. The MS board also had a different arrangement of the Insert, Delete, Home, End, Page Up and Page down keys; on the the Logitech they're in a "standard" 2X3 arrangement.

If you only use one computer, the key layout is no big deal. If you use more than one, the differing layout can be very annoying.

FWIW, I also prefer the shape of the Logitech mouse.

Update: The batteries in the mouse lasted about 4 months; pretty good considering that the LED is always on. The batteries in the keyboard are still going strong. On average I use them almost daily for 1-2 hours/day.

We burn through a lot of keyboards: the only complaint here is that the keyboard is noisy, with clattering, and that can be solved by one of those soft plastic key-cover things.
Okay: the wrist rest is comfortable. The buttons at the top let you log off user (which shuts computer down, be careful!) pulls up email, Instant messenger/sms, Webcam, Media, will mute colume, pull up your home page and do a computer search!

The mouse is great: now everywhere I go I'm trying to spin a wheel to scroll down, this is so convenient.

Altogether a great keyboard/mouse combo.

I've been using the original MS Natural keyboard for years and I love it. But I wanted to go wireless so I bought this set. Unfortunately, it falls far short of being functional. Overall, the keyboard and mouse have a nice solid feel to them. The keyboard especially has a nice feel to the keys. Reception has not been a problem at all.

Here are the problems:

Keyboard:
1. The strangely laid out home/end/pg up/pg down/insert/delete keys that everyone has mentioned.
2. In order to conserve space, the different key pads are placed uncomfortably close together. The letter keys, the home/end/cursor keys and the numeric keypad are so close together that they are almost one continuous keypad. This makes it difficult, tactily, to move from one set of keys to another. This sort of defeats my purpose, which was to buy a full-sized keyboard for my laptop. For instance, when I use the page up/down keys, I have to be careful not to press on the numeric keys. These are not things I need to be thinking about when I am touch-typing.
3. Again, a space-saver issue. They have brought the function keys right down on top of the letter keypad and the scroll-lock/print scr/pause keys down right on top of the numeric keypad. I use the numeric keypad a lot and because they have basically added a 6th row of keys at the top, my hand is always positioned on the wrong keys and I'm typing all the wrong characters. Same with the function keys, which I also use a lot. Not only are they right on top of the number keys of the keyboard, they have these sort of random spaces between them, which again, makes them very difficult to use when touch-typing. With this keyboard, I've been forced to resort to hunt-and-peck typing a lot.
4. One last negative. Yet again, a space saver issue. The right shift key has been reduced to nearly a "normal" letter-key size in order to squish the cursor keys right up against the letter keyboard. This makes the "enter" key stick way out past the shift key. And again, tactily, I constantly end up pressing Enter instead of Shift because the shift is a good 3/4 inches in from the end of the Enter key.

Mouse:
1. Huge mouse. Not good for small hands, which I have. It is also a right-handed only mouse. So if you're a lefty, you're out of luck. I'm not a lefty but I mostly use my left hand for the mouse and I switch to my right, when my hand get's tired. It is nice to have that versatility.

I suppose once you get used to these inconsistencies, it would be an adequate keyboard. But I wonder why I should have to relearn to type to suit Logitech's quirks? P>The one thing that the old MS Natural keyboard and that none of these new split keyboards have is the reversed "stand" (can't think of a better word) where it tilts the keyboard AWAY from you rather than toward you like they all do now. When the keyboard is tilted away, it is much much much more comfortable. I have seen other people mention this as well. I wonder why they did away with that excellent feature. Right now I've propped up the Logitech with a piece of wood under the wrist pad. Makes a world of difference.

I'd been wanting to get an ergonomic keyboard for some time, as I type an awful lot and I thought I'd give it a try. I found this Logitech combo (Logitech's a name I've used and found dependable) that was cordless to boot, and perfectly competitive price-wise with wired devices from other makers. I couldn't be happier. I can't believe I waited so long to go ergo, and to go cordless for that matter (well, cordless headphones still suck). This combo has worked flawlessly for me. The software is just perfect, letting me adapt all buttons on mouse and keyboard to my needs--on a Mac no less, the last, and only, bastion of one-button mouse design. I tested the keyboard to see how well I could send commands from a distance. I was amazed to find that not only did it work wihout a hitch at 6 feet or more, but also even facing in the opposite direction against a wall. I think these products prove beyond a doubt that cordless input devices have finally made it--prove to me at least for sure. Highly recommended.

I highly recomemd this product.As fare as I'm concern is best deal for the money.

I had no problems with installing this mouse, and kind of liked the function of the small button, which lets you flip between open applications. The problem I had, which made me return this mouse the next day, was the fact that my hand went numb after using it for half an hour (to be fair, I have had tendinitis in my wrist and elbow before, so I may be more sensitive to a mouse shape than others). The scroll wheel was a little further back than my other mouse, the buttons were set back from the front a little (so my hand could not rest over the front of the mouse and still hit the buttons), and the shape was not comfortable. This mouse will probably fit great in a woman's hand, but not in mine. I'm no giant, either (I can palm a volleyball with ease, but not a basketball). The Labtec Optical Mouse, at ..., is a far better deal. I can't notice a difference between the two as far as speed and accuracy are concerned.

We needed two new mice -- one to replace a broken one and another that was wearing out and was a bit big for my wife's hands. This mouse was a good fit for my wife's hands. For my medium size hands, it also worked well. The mouse buttons require just a tad of toe-in, but hardly noticeable. The wheel is a little clicky when rotating, but not too much. The middle button on the unit (not the normal button, but a special one) was basically useless. It could only be "programmed" for specific functions (run, scroll, minimize, close, etc.) and not to call up applications like hotkeys that I am used to and the box led me to believe. Combining that with the fact that the drivers for that functionality also would not work properly with Windows XP Professional when going from non-Admin to Admin, nearly made me throw it out the window. I went to the Logitech site and there were no updates for the mouse. Also, the wheel was slow in responding (scroll and then wait half second for it to actually do it). So, I removed the specific drivers and using the native Windows XP drivers, the mouse worked fine and so did the wheel. So much for the extra button which probably added [money] to the price (not exaggerating). The uselessness of the "extra" functionality and the higher price would almost cause me to give 3 stars. However, it is better than other mice that would get 3 stars and the form and fit are good, so 4 stars.

Accurate little optical mouse. I plugged into an xp laptop and it worked right away (i didn't install the logitech software). The scroll wheel is stiff and loud, but the minor modification described in one of the previous reviews worked great.

this mouse replaced the microsoft basic optical mouse (same retail price) which never worked properly (the pointer would jump around constantly).

My old CTO swore by the original Expert Mouse(all white) and replaced them every couple of years as they tended to not last very long. When the new Expert Mouse Pro appeared with scroll bar and quick launch buttons, I requested one through my IT department. Here were my observations:

Pro's:
(1) The best alternative to regular mice, period. The biggest and smoothest trackball there is. Very easy to use and great on the wrists.

(2) Good looks.

Con's:
(1) VERY pricey. For what it is, I have to imagine that Kensington is making a killing on these. The price is too much to bear for me to purchase it personally. Given that I spend more hours computing at work than at home, it's appropriate that I need it at work, but not at home.

(2) The scroll wheel is not placed in a convenient spot, thus I found myself not even using it.

(3) Quick launch buttons. Again, not very convenient to have to raise your entire hand off of the trackball to push the buttons.

(4) Not "solid" as the original. The original seemed better made and was heftier, thus would not move as often as the Pro version.

Summary:
I am ALL for ergonomics, especially for those who make a living at computing. I own a ...Kinesis ergo keyboard which I find invaluable for everyday use. It's not great for games, but at least it helps me to break my gaming habit :) With the right combo of seating, monitor placement, keyboard, and mousing, you should be able to effectively avoid RSI. The Kensington product is great for that purpose, but the cost will be prohibitive for some, in some instances. The Expert Mouse with some modifications and lower price, should be the office worker's pointing device of choice.

After 20 years as a heavy computer user my right arm, elbow and wrist just started to go. I immediately started paying attention to ergonomics. My three best purchases were a good chair; the MS split keyboard and the Kensington Expert Mouse Pro.

Although I see some complaints here about quality, mine has functioned flawlessly for over a year now (knock on wood). The ball pops out easily for cleaning with a soft cloth and a squirt of compressed air cleans the contacts. Two minutes to clean the thing.

I switched to trackball to start mouse-ing with my left hand. The transition was easy. The Kensington was easy to install, configure and use. The mouse has four easy-to-program action buttons and a scrolling button. I set mine to left-click; right-click, double-click and show running applications. Since your hand rests on top of the ball it's easier to click the buttons and a lot less stressful on your wrists. Pressing once for double click is a godsend. "Show running applications" allow me to hide the task bar and gain another 5% of screen real-estate.

There are also 6 buttons on top of the mouse that will activate any task you want. I'm using mine to pull up a couple of favorite web pages and applications. Since my MS-Natural keyboard has a dozen buttons I'm finding I mouse a lot less and my wrist and arm have healed. I've also learned to use the "windows" short cut keys, especially CTRL-a,x,c,v (select all, cut, copy, paste),

The Kensington menu also has click speed, scroll speed, rest reminder, pointers, and acceleration and movement options. I find the rest reminder very helpful. A custom message pops up at your pre-set time to remind you to get up and move around! I've got the movement set to snap to the default button on the page which is usually very handy. I'm not sure why some users are complaining about the scroll button. I agree with some users here that the scroll button takes some getting use to since the scroll button makes this a 5 button mouse! But, you can set one of the action buttons to auto scroll as an alternative. I set the scroll speed to "very slow" and that helped a lot (1.8 Athlon here).

The mouse does take up 8K in background processing, but in this day of 128K RAM that should not be a problem.

Overall, I am very happy with my purchase and my wrists are estactic!

love mine... i have one for work that sees VERY HEAVY USE. i got it after a couple of our ITS guys recommended it since i do a lot of programming & desgin in addition to accounting... this product works equally well with both Mac & PC without any difference between the two. The buttons & scroll do not work on either system for me, but that is because i have a KVM to switch back & forth between my two systems & those do not play well when you mix Mac & PC programming... if i hook this up to one or the other system, it works awesome on both, however. My hand used to get stiff or go to sleep on me with an old mouse, but not with this.

I am a techno-geek. My wife is not.

She just doesn't like seeing a coffee table with four remote controls (TV, Cable Box, DVD player, TV) on it. She loves to watch movies on the home theater, but there is no way she can ever set it up to work correctly, and so if I don't do it, it doesn't happen.

This device is unbelievable! It took me about half an hour to gather the names and model numbers of all the various components of the home theater, and then enter them into the website of the manufacurer (go to harmonyremote.com to see exactly how easy the setup is). Then, the remote is updated by the USB cable (included) you connect from the remote to your internet-connected PC. All the settings of your components and the remote-control language that came with each component is updated into your new all-in-one remote. The update is done in a matter of 45 seconds (cable internet connection), and then it's ready to go.

It is organized by activity rather than by device. This means there is an actual button that says "Watch a movie", another that says "Listen to CD", etc. It can even control things like minidisk players, DAT playes, CD jukeboxes, satellite boxes, etc. If you have more than one music source, you can control multiples. And if you have both cable and satellite, you can make a "Watch Cable" and a "Watch Satellite", for example. It can even control projectors, combination devices (TV/VCR, DVD/VCR's, for example), switching devices, and even your room lighting or fireplace(if they have an infrared control)!

When you pick "Watch a movie", for example, it will turn on your TV, set it to the proper video input or tune the correct channel, turn on VCR, turn on receiver and set signal source to VCR, and change the remote control keypad to a VCR controller. If this sounds like gibberish (and to my wife, it does) get this device.

The setup is so easy, she could have done it herself (but she was afraid to try because the thought it would be too hard). It was absolutely painless.

Summary: If I could give more than 5 stars, I would.

I have to say that I have used now about 3 universal remotes and was about to give up and continue to use the 4 that I ordinarily need until I read about this one. The 659 is in one word - Spectacular!!!

I am an average computer user and bought this remote online about 3 weeks ago. All I can say is that it took me 15 minutes to set up out of the box FULLY PROGRAMMED!!! That to me is unheard of instead of programming and reprogramming silly numberic values to a remote which would take me days to figure out - I was again up and running with the Harmony in 10 minutes.

The remote is completely user friendly and intuitive here are my pros/cons on the remote:

Pros: 2 things set this remote apart:
(1) Great, Web-based configuration with a vast database of electronics devices. Forget about punching in obscure codes into your remote -- just select the Manufacturer and Model of your device, and you're off to the races.
(2) Activity Keys -- the simplicity of just pressing "Watch TV" or "Watch Movie" cannot be underestimated. No more powering up components, switching inputs on the A/V receiver and the TV. Just press one button, and you are doing what you're supposed to be doing: using your gear. The Harmony Remote was designed simplicity and a great experience for the end user -- not the techno geek. I bought one for my brother and brother in-law this week as gifts!!!!

Cons: I have used it for 3 weeks and have yet to find a fault with this remote.

For those who write negative comments - my only guess is that they are not computer frinedly at all b/c all you need to do is install the software and follow the prompts and you are done!! Truely a great experience in a market that is full of disappointment.

I just purchased this remote last week. So far I cannot find any problems. The remote operated all of my devices right after the initial programming. I went from 6 remotes to 1 in about 2 hours. One of these devices was my Linksys media adapter which remote I never thought I would be able to eliminate.

It did require some tweaking through the help menus on the remote and through the online programming. After about an hour I was able to get my most used buttons and commands available and up front on the main screens. Once I got used to the online programing the process became easy.

I have not tried any command-learning because all of my devices worked. Which I found to be amazing because even the odd and seldom used commands for my Onkyo reciever and Linksys adapter were pre-programed.

I am working with Tech Support to fix problem with the Media function that lets you see what TV Shows are on. Tech support has always responded within 24 hours and we seem to be progressing towards a resolution. The problem is software related not hardware.

Beware where you purchase this device: Not all online retailers are authorized retailers and if they are not authorized then you have no warranty. I bought mine through JR's electronics who is an authorized retailer.

I love my Microsoft optical mouse. I like the ergonomic form, the scroll roller, and the ability to set the speed and clicks of the two buttons accurately. However, I am now using the second one in about five months.

The first sign that I had of the first mouse's unstable connection was that my system would lock up. It required a complete shut down (cold boot) for the mouse to work. I scanned for viruses, checked my drivers, and was rewarded by the flickering mouse that lasted a few more days. The next step in my diagnosis was to remove several programs from startup; the mouse "squeaked" along nicely, but I noticed that the optical element was hot. After a week of rebooting and keeping the mouse in a cool dry place it died.

Because I liked the feel of the mouse, I bought a replacement. A day after my mouse was installed the second identical mouse in the house experienced the death knell. This one was replaced with a product from a different manufacturer. The mice are very similar.

Does the convenience of a favorite tool make up for the frustration of one that fails? Maybe it does since I went right out and purchased another. Because there are now two optical "mice" in the house, by two different manufacturers, I have time to decide what I will do next time.

It is highly possible that my first mouse was a lemon. The coincidence of the second mouse dying in approximately the same amount of time (five to seven months) is uncanny. Does it mean that the problem is circuitry within the mouse or the power source in my house.

Microsoft has so much confidence in the product they will take care of problems for three years. This tells me that I may have just been unlucky with the previous two mice or I did not realize that it has delicate circuitry and abused the poor thing. I did not take advantage of this warranty, which was my mistake.

For me it rates three stars. The new mouse is a five star jewel -- so far... so I guess it is 4 stars for the mouse.

I bought this product when my old ball mouse went kaput on me. So far, I'm happy with the optical mouse. It glides effortlessly across the mousepad, unlike my old mouse. What I like best about the optical versus the ball is its maintenance. I don't have to worry about dust and particles finding their way inside the mouse. Therefore, I don't have to take it apart to clean it, as I had to do with the old mouse.

The scroll wheel was cumbersome at first; however, if you click gently on it while the cursor is pointed in the scrolling area, it works just fine. This mouse comes with software, although it works fine without. It also has an adaptor, which allows you to hook it up to a USB or PS/2 port. I haven't tried it on my Performa yet, but if it works I think I'll go out and buy another one.

This is by far the best mouse I've ever used. I have one at work and one at home. It glides smoothly on just about any surface but if you want the best control and feel use a mouse pad. The only caveat is you can't use it on a mirror or clear glass surface. That's not a problem for me and I'll never go back to the old ball mouse.

Because of brief experiences with Microsoft ergonomic keyboards, I intended to order the cordless ITouch (nonergonomic) instead of this; however this was the only one in stock and I ended up getting this one... The keyboard is really nice. As another reviewer mentioned, the slope of the keys feel much more natural than the microsoft. However, I have to disagree with the previous reviewer about the layout of the home/end/etc keys. If the keys have to be in a vertical layout, this layout makes much more sense than the microsoft's - microsoft arranged the keys in a seemingly random order, while logitech left most of the keys in their standard place.. (insert/delete and page up/down are where you'd expect) The cordless mouse is also far superior to microsoft's - the movement is much smoother and more responsive. I had to take off one star for 1) the "logitech" key seems to randomly think it's pressed once in awhile and pops up an annoying help page; 2) when i play some games, in order to get a decent response time from the keyboard i always have to press the "connnect" button after every reboot both of these problems are probably driver/software problems, but they're annoying

I tested over 20 keyboards before purchasing this one, and fell hopelessly in love with the way the keys felt. Forget about the cool radio technology, or the fact that this is an "ergonomic" keyboard, or even that it comes with its own mouse. It's just a pleasure to type on.

I was skeptical of the radio technology which makes the keyboard portable. I thought it would work, but with occasional glitches. Yet I honestly can't tell a performance difference between this technology and having a plug-in keyboard. If anything, I've noticed that the included mouse is more accurate than my old Logitech First Mouse Plus. And, as with the keyboard, it just *feels* better.

As an ergonomic keyboard, this board's chief competitor is the Microsoft Natural Keyboard Pro. I really wanted to like that keyboard. It was a good deal cheaper, had more function keys and even a couple of USB ports. But there's something about the curve of the board that's just awkward. The slope is not as subtle as this one, and those severe angles make typing harder somehow. Worse, the keys are very much noisier.

And the MS Pro's apparent advantages largely disappear on closer examination. The MS Pro seems to have more special function keys than the Logitech. In particular there are a number of web exploration keys that the Logitech seems not to have. But Logitech has put additional web surfing help into the mouse. Press down on the mouse wheel, and a convenient palate of web surfing tools sprouts up. Also, the MS Pro's USB ports aren't that much of an advantage. Because you have to plug the keyboard into an existing USB port, you expand your total ports only by one. That leaves only price and a single USB port as the net advantage of the MS Pro.

To me, that means Logitech wins hands down.

Once you let yourself get used to the ergonomic design, you wont go back to typing on a standard board again. It's akward at first, but keep at it. Your hands will never tire, you wont get carpal tunnel and you feel more relaxed at the end of a long day of typing. I love the freedom from cords, both with the board and especially the mouse. Again, give the mouse a fair try, and you wont go back to a standard design. I love the center scroll and thumb back button.....( that's how I have mine programed)
I started with their wireless mouse, then onto the "Cordless Trackman Wheel ( I dont care for that one) then onto the Cordless Desktop Pro. One interesting thing, I can use the cordless trackman wheel at the same time I use the cordless mouse. No separate programing, or hookups. Both work off the same remote receiver.
Anyway, I'm on my computer an average of 10 hours a day, 7 days a week. I've only had to replace batteries in my units TWICE in the last 2 years!!! No, I dont do much gaming, but I do lots of photo editing.....anyway, I use Duracell's and have had good luck with them in these units.
Again, once you finally get used to the board and mouse, you literally cant, and wont want to type on a standard lay out as Your hands will feel akward and uncomfortable....
I love this unit and hope others will give it a try. They wont regret it.

The one I purchased arrived defective. It took customer service almost 2 months to fully correct the problem and send another unit.

When it works, it's a great device. Good range and has the key features for a good presentation.

I really found this remote to be perfect for what it's supposed to do, run PowerPoint. It has a nice look, fits perfectly in the palm of your hand (as opposed to my old, bulky remote that I found myself fidgeting with), and runs PowerPoint like a dream. I have free range within my training room and quick response to commands. It is also is very easy to use with a simple layout for the technology impaired user.

The only warning that I would give anyone is that the RemotePoint Navigator is designed to run PowerPoint and nothing else. If you want it to run other programs, you're better off looking for something else. In my organization, many of the subject matter experts produce their own slide shows for training or presentations. Many of them prefer to use Corel Presentations over PowerPoint (I don't know why). This remote doesn't work well with Corel Presentations because of the commands.

However, if your only goal is to run PowerPoint, I highly recommend this product.

I do a lot of speaking - workshops, keynotes, etc. - and recently bought this to replace my old serial-port remote. It works like a dream from both close up and while wandering in a big room and does everything it needs to for a reliable PowerPoint presentation. As a bonus, it is really small. The remote, batteries, and small USB stick fit into its own bag, which is smaller than a glasses case. I am more than happy with it and would recommend this product to anyone looking for a small, reliable, and uncomplicated PowerPoint remote.

One small recommendation - be sure to remove the batteries when you're not using it. Any jostling during your travels will push the buttons and wear out the batteries. Of course, this advice would be the same for all remotes. I just had to learn it the hard way!

Just a quick report on my experience with this mouse. I'll start off by mentioning that perhaps I had unrealistically high expectations...
First off I should mention that I already own it's sister mouse, the MX700, which I use with windows XP, using the standard generic drivers - i.e. I didn't install the Logitech drivers. It works great!

I recently got an iBook with built in Bluetooth. It seemed that the MX900 would be perfect - A great mouse, no wires, and also a bluetooth hub which I could plug into the winXP box and use for wireless internet between the two computers (Yes it CAN be done).

Well the MX900 connected to the iBook easily enough. I got the 4th & 5th buttons working with Expose, but the mouse doesn't move right. When plugged into Apple's bluetooth it develops really horrible acceleration, which make it a real pain to use :(

Anyway I though so long as I can get the wireless internet to work then I won't mind so much. After a lot of messing around I got a bluetooth network set up on the winXP desktop machine. After even more messing around I got as close as it seems possible to get to getting Bluetooth networks set up on OS-X. Basically OS-X doesn't really support them I found out :(

So I'm going to return the mouse. Hopefully I can swap it for a normal wifi router - I just won't have a cool mouse to go with it :(

Oh one weird thing I noticed - the build quality of the MX900 (bought in the US) isn't as good as my MX700 (bought in the UK). Bizzare seeing as they look essentially identical. The MX900 just feels cheaper, the buttons rattle etc.

However I should add that if you intend to use the mouse for a normal destop PC then it's still a great purchase, and probably the best mouse you can buy - I think the extra $40 (over the MX700) is worth it for the bluetooth - if you need it.

I got this mouse with the Logitech diNovo Media Desktop which came with the bluetooth hub and a keyboard and media pad. The only problem with the mouse is that the software that lets u assign keystrokes to the buttons on the mouse actually disables the middle mouse button (mmb). I use programs that require the mmb and was wondering why this didnt work until i shut down the program SetPoint from my system tray. Doing so will render the quick switch button inactive but i find it faster to switch programs by pointing and clicking then by pressing a button then pointing and clicking. Without the program all other buttons work as normal. I dont need to assign special tasks anyway.

Another point of interest is the battery life. I have the hub which recharges the mouse which is a must because if u dont keep it charging when not in use it will run out. U can check ur batteries by running the SetPoint software and it allows u to check batteries for the mouse as well as the keyboard and media pad if u have diNovo.

All in all, its a great device if you use bluetooth, but if u dont need or use bluetooth you are probably better off with a regular cordless.

I love this mouse. I use it with my laptop everyday. My Dell laptop has an internal bluetooth receiver thus making this small and easy to use. I have to charge the mouse on the hub once a week, however I really don't mind too much (I keep two extra dbl-A batteries in my laptop case). I do have to make sure to remove the batteries when I'm on the go (or the batteries will drain from detecting movement). This mouse is not suitable for left-handed people. I like the weight it has (not lightweight, but not too heavy). Its range is great (thats bluetooth for you).

One mistake I made once was that I tried to install the Logitech software in my WindowsXP (If you just use the bluetooth software that comes with your laptop, it will find the mouse just fine). The software disabled my internal bluetooth device in the laptop and I had to use the hub in order for the mouse to work (not acceptable - otherwise I would have purchased the mx700). It took me a while to figure out that it wasn't just the Logitech software I needed to uninstall, rather I needed to remove the bluetooth hub software as well (very misleading by Logitech).

I only rated this 4/5 stars due to the short battery life. Still, don't let that deter you if you don't mind working around that (I don't mind - I was well aware of it from reading posts on here).
