Summary: Cheap Wireless Goodness
Review: A surprisingly good wireless offering considering it's price. I have yet to experience any connectivity problems, and it has a decent range. The most surprising aspect is its accuracy. I have yet to experience the lack of accuracy that a lot of people complain of with other wireless mice that are even more expensive than this one. It's also pretty light considering you have to stick two AA batteries in there.A surprsingly good offering from Micro$oft, considering its price. Highly recommended.

Summary: Great Mouse!
Review: Although a bit on the heavy side, it has good functionality. It scrolls smoothly with great tracking speed! Installion was a breeze and batteries last well. I'd say, it's worth it but the tilt wheel is just a gimmick.

Summary: Misprint ... 3 Foot Range should read 3 inch range
Review: Amazingly, I didn't really read the tech specs for the MS Optical Wireless Mouse version 2.0 before I ordered it. Unbelievably, the documentation says the wireless range is 3' (ie: 3 feet -which by the way is pretty useless). I had ordered 2 of them for computers in conference roomb. Both of them worked ok for about 5 minutes, then started getting hung up and the pointer wouldn't move .... rebooting and reloading ensued, then, I found that if I move the mouse to within 3" (That's 3 INCHES) the mouse works fine... I can move it outside of the 3 inch range and it starts hanging up. Fresh batteries...nope, same thing. Changed the Mouse and RF receiver channels, same thing still.......So, I hooked up the old trusty Logitech RF Keybd and mouse that I've had for about 5 years and it works fine, up to 14 FEET away. (so the MS problem isn't radio interference or anything apparantly, it is just shoddy craftmanship.

Summary: Pretty Darn Good (in Spite of the Company)
Review: As much as I am compelled to bash Microsoft for their buggy software, I can't help recommending this mouse. A previous reviewer noted the different shape, but to me the shape actually gives you the sense of a more secure grip on the thing. I admit though it took a few weeks to get used to. My only other observation is a lack of feedback in the scroll wheel. In the old wheel mice you could feel a slight notch at each increment that you rolled the wheel. Not so with this one. So this too takes a bit to get used to when estimating how far you need to roll the wheel in order to go half-way down a page. But those are truly minor quibbles. The installation was a breeze, and it does go easy on the AA batteries. The tilt wheel is a bit of a novelty, but it actually does come in handy on occasion. As far as optical mice go, it is very responsive. You certainly can't go wrong on the price. If you've never used an optical mouse, imagine never having to clean crud and dust bunnies out from inside around the mouse ball. Overall, I'd say if you're in the market for a new mouse and don't need buttons all over it (like the more expensive wireless Intellimouse), snap this one up.

Summary: Excellent value
Review: Bought this great mouse in January and although I use it approximately an hour a day, maybe two....the original batteries are still going strong. Very easy to use and a pleasure not having the wire in the way.

Summary: Very Very Very comfortable!!!!
Review: Did I say it was very comfortable?? :)
I bought this mouse about 6months ago and I didn't have to replace the battery yet!!! Amazing! and i use it 5 to 6 hours a day! I suffered from carpal tunnel syndrom and my doctor recommended I buy this Microsoft mouse. Since i started using this mouse, i don't feel any discomfort from using my computer. And because it was designed by Microsoft, i had no compatability issues with my computer.

Summary: Excellent product!
Review: First, let me address a couple of issues that previous reviewers have raised. The drivers: Yes, you do have to unload the existing mouse/touchpad drivers if it conflicts with this one, but that does not make your old mouse/touchpad non-functional. You may just lose some special functions, but the basic functions should still work just fine. The transceiver part: Did you expect that 'wireless' meant 'magical'?? Of course there's gotta be something for this mouse to communicate with, and that is a mouse sized piece with a 3-4 foot cord. This can go almost anywhere near your computer (away from the monitor & CPU preferably). Just set it and forget it. Mine required no frequency setting at all, it just worked. There is no ball, only an optical sensor which looks at the surface you use it on to determine if its moving. It must be used on a surface that has some texture/pattern to it. A mirror or highly polished surface, or something completely plain (like a solid colored counter) won't work properly. But you can use it on fabric (pant leg, shirt, bedsheet, etc), your hand, your dog, etc. ALMOST anywhere. The sensitivity is great, the scroll wheel has some tension to it, so it doesn't just spin like the old versions would. Its sort of like having a car with some road feel to the steering vs. one that you can steer with one finger. It gives you better control to have that little bit of tension, and I like no clicky noise. Ergonomically, I think it is shaped well for my large hand. Smaller hands may not work as well (e.g. kids, petites) reaching the buttons, etc. Uses 2 AA batteries, which I think is great. Easy to find and cheap when you need to replace them. No waiting to recharge or $10 special batteries to buy. All in all a great wireless optical mouse. I highly recommend it.

Summary: poor ergonomics
Review: I acquired one of these mice in a Microsoft Optical Desktop 2.0 bundle.
The scroll wheel also scrolls sideways, but this is of little practical use; it also requires far much more force to use it as a middle mouse button that it's useless for gaming.
This model is much higher than most normal mice I'm used to, and I found myself getting a sore hand after using it for more than half an hour.
If you're after an ergonomic mouse by Microsoft, consider one of the newest series three Microsoft IntelliMouse models. If you're after a decent symmetric pointing device, consider something simpler such as the Microsoft Wireless Optical Mouse.

Summary: Perhaps the worst mouse i ever had!!!
Review: I bought this mouse as part of the wireless desktop 2.
I'm extremely happy with my new keyboard but i really hate this mouse. it's bulky, it's slow and the middle mouse button requires actuall pressure until you here a click for it to work properly.I will finish saying that the tilt feature is probably the most useless gimmick ever.I love microsoft mice i always had a microsoft mouse and my favorite one is still the blue optical USB one. I prefer a mouse that fits comfortably in my hand and feels like a natural extension. no matter how much time i gave this WOM2 it still feels like an uncomfortable piece of junk.

Summary: Warning! Worked for a while then sucks!
Review: I bought this wireless mouse a few months ago and have had numerous problems. This mouse just plain hasn't worked for me. I've tried every type of surface known to man and the mouse still has problems working properly. Buttons don't work, my left-right scroll doesn't work, pointer doesn't move correctly. My old Microsoft wired optical mouse was fine on the same surface. I seem to have good connection and battery, but can't continue to fight with this thing. I'm plugging in my wired mouse. I do have a Logitech wireless at home and it works great. Make sure you really shop around before you buy.
