This is a no-nonsense great mouse. Feels good in your hand, good grip, great tracking on-screen, and it just works. We got one for our laptop and we love it!

I bought this mouse to use with my laptop when I'm working at my desk, preferring a mouse for some tasks. Unlike others, I had no problem with the mouse's tracking or scroll wheel. The scroll wheel has a good feel, as do the buttons. The mouse fits well in my largish hands (big palms, stubby fingers). The problem is in the driver. The driver supplied with Windows XP (no driver is included in the box) crashes a lot, causing a hiccup in my work. The mouse stops responding for a couple of seconds, then I am prompted to send an error report to Microsoft. I downloaded the latest (as of 6/1/2007) Intellipoint driver from Microsoft, and the crashes actually increased in frequency. An OEM Dell unit (optical, scroll wheel) plugged into the same system never crashes.

The Microsoft mouse is fine as a mouse, especially for the low price, but the software doesn't work, at least on some systems.

i've come to expect a decent level of quality when i buy a microsoft product but this mouse seemed like it was just some generic rebaged mouse. the main problem is when it is on a slightly uneven surface, and i mean very slight or on one that is too shiny the laser won't track right. i had to open the thing up and shave down part of the optics assembly becuase whoever designed it didn't test it well enough. unless your willing to do that skip this one, it is not of the same quality as the first generation microsoft optical mice. i know everyone is doing what they can to cut costs but at a certain point your robbing peter to pay paul. but then again you do get what you pay for :/

I used this mouse for a couple of weeks before it drove me nuts. The thing skips around all over the place - even when the mouse is sitting perfectly still on a flat surface the pointer was jumping around. It became impossible to even click an icon. I ended up buying a Logitech mouse, but this one was so cheap it wasn't worth returning. I know Microsoft products are usually very good though so I must have just had bad luck with this one.

I bought this mouse for my fiancee about three months ago and she has not complained once. She uses it extensively in her office and reports that it is accurate, comfortable, and looks sharp.
