Summary: I'm not going to argue, but...
Review: Hey,What's with bashing Microsoft mice? I own a Microsoft Trackball Explorer, and it works just fine, no "cheap" noise or anything. I'm not saying this mouse is bad though, cause it couldn't get this good a rating if it was bad. I suppose it's all a matter of preference. Also, my Microsoft mouse refreshes at a rate of 1,500 times/sec, which, if I remember properly is...150 hertz? PEACE!!!

Summary: A Good mouse but......
Review: This is a good mouse but it dosen't track well on my glass desk. I was forced to use a mouse pad even though the reason I bought an optical mouse was to get rid of my mouse pad.

Summary: This is a great mouse!
Review: I recently bought this mouse as a replacement for the mouse that came with my VAIO. This mouse is amazing. I use my PC for many hours each day and it's extremely smooth. Also, I use it to play online games such as Counter-Strike. This mouse isn't too small, or too big, it fits perfectly in my hand. I think this mouse is great and I recommend it to anyone who is looking for a new mouse!

Summary: cool little mouse
Review: The mouse is light weight and has a bright red light on the underside of it, it is pretty, and smaller than I thought. You can use it on your legs or chair shoulder with no problem. I connected via the ps/2 and did not have to install any software, I just took my old one off and replaced it with this new one.

Summary: If the Swiss made mice, they'd have this kind of movement
Review: I have bought an insane number of pointing devices. I'm not sure why that is, exactly, but I'm sure that therapy will probably be needed to unravel the mystery. The practical upshot, however, is that I've owned and/or tested just about everything that's come on the market in the past few years--and this little device is right at the top of the list. I find it to be far superior to its Microsoft competitor, which seems to be less fluid in its movements. Often, I've had to pick up the Microsoft Optical mouse from the desktop surface in order to "reset" it. Plus, when doing detailed graphical work, the Microsoft's tendency to randomly jump a few pixels is really annoying. Maybe my particular Microsoft mouse is a slight lemon, and in fact there's nothing generally wrong with the device, but for whatever reasons, I've had much fewer problems with this Logitech version. It's easily the most fluid, responsive pointing device I've ever used--outside of a graphics tablet. I am baffled, somewhat, by other reviews which comment on it's less-than ergonomic design, or its appropriateness for small hands only. After all, an "ergonomic" mouse almost certainly means a mouse that is designed for right-handed users. This more egalitarian design can be used by hands of all persuasions. Nor do I notice any unusually "cheap" clicking sound when I press the mouse buttons. It is certainly slightly louder than other mice I've owned, but it's hardly a sound connoting bad construction. About the only problem I've encountered with the device, in fact, has to do with the controlling software. If you're buying this as a replacement for a Logitech device already installed on your machine, you do have to take care to uninstall all that old software before proceeding. I found that one game I play got really confused when I just installed the new Logitech MouseWare over the top of what was already there. All the problems cleared up, however, when I manually uninstalled all Logitech MouseWare and then did a fresh install. Having said all this, and recognizing that the cord provided is a fair bit longer than most mice provide, I am intrigued by the future availability of a cordless version. I have a cordless Logitech roller ball mouse, and like the freedom it offers. If Logitech manages to pull off the same fluidity with the cordless version that they have with this one, it will be very hard to continue to prefer this one. In the here and now, however, I really doubt you'll find a better, more precise mousing experience than the Logitech Wheel Mouse Optical.

Summary: Too narrow to be comfortable, unless you have small hands.
Review: Optical mice are great, for the reasons everyone else is saying here. There are two annoyances with this product, however. If your hands aren't tiny, the mouse will be too narrow. This is a problem because it is much more tiring and possibly painful to grip a narrow mouse over an extended period of time than it is to grip a wider one like the Microsoft mice. The second annoyance is fairly trivial--the mouse emits a noisy 'clink' that sounds a little cheap when you press the buttons. I got this mouse for a computer I'm building for my girlfriend; I have both a Cirque touchpad, which is my absolute favorite pointing device, and a Microsoft Intellimouse with OptiEye, a discontinued optical mouse that is very nearly the same as their other optical mice. It is very comfortable, and works great. If you ever experience any sorts of pain associated with mouse use, I highly recommend using a touchpad instead. The benefits are that you don't have to grasp ANYTHING, you can move the cursor with a very slight touch, and you don't even have to beat the tips of your fingers up from constant clicking, since the lightest of taps on the touchpad surface achieve the same result. In addition, you can set a touchpad on or against your leg at the same angle that your hands naturally rest in at the side of your body, rather than twisting them to the horizontal surface of a desk. The bottom line is that the tingle I was feeling in my hand, wrist and lower arm from constant mouse use went completely away once I started using a touchpad. Like an optical mouse, there is never any cleaning or moving parts, either, which makes them much more reliable than other mice or trackballs.

Summary: Amazing
Review: This is the best mouse ever. Optical mouse technology has tranformed our design office into a friendly club as we could get rid of the desks and tables whatsoever. Now we are sitting in comfy armchairs, with lightweight keyboards on the knees, and the Logitech gizmo on the arm of the chair. The product's only competitor, the Microsoft Intellimouse is bigger, uglier and definitely more expensive. You could analyse its excellent performance for hours, but I believe it's not necessary. This mouse simply becomes part of your body, eliminating any obstacles on the way from your mind to the screen. The only drawback is that by using it you completely forget the fact of a physical pointing device and sometime tangle up with the its cable. The cordless version will be on the market later this year, so even if I tend to think of it as an ultimate solution for mousing tasks, I will surely be a customer of its cordless version.

Summary: Smooth Operator
Review: Without getting the plug-n-play to work on my SCSI port, for[an inexpensive] mouse having OPTICAL functionality, I gladly "settled" on using the PS/2 adapter, with no apparent loss of performance. The scroll wheel is a bit rough, but the tracking is extremely precise and predictable. This mouse is an excellent value for those who want to step up to optical mouse technology.
