Easily replaced the previous wired Microsoft mouse I had. It's a little smaller in size than that one, but I quickly got used to it. At first, it was quite a bit more sensitive to movements, but with a few clicks on the button above the scroll wheel, this was fixed. The only negative I find is that the left-right movements of the scroll wheel are perhaps a bit more sensitive than I would like, resulting in the back-and-forth in the browser being accidentally activated at times. However, this wouldn't make me not buy it again.
