Summary: Nice medium sized mouse. Scroll wheel moves very little from one position to another, which takes is fairly easy to get accustomed to, but is good for scrolling through large documents. I wish the mix of rubbery and non-slip hard plastic was all rubbery, but not a big deal. As with most Logitech mice, works great for a few years, and then all clicks become double clicks and is ready for replacement. So be sure to get this on sale, since it will not last forever.
