I got two Logitech mice, and they worked rather nice. But then buttons started acting funny on first, then second, and I switched to Genius one (probably with lower resolution sensor). I quickly found that I have two mice with working sensor, and one mouse with working buttons. Not good.
Now, I got new Logitech M90.. this one has working sensor, two working buttons, and three legs of the same length. Ouch. It wobbles on table :-(.
It also shows why mouse-box is cool-looking, but not quite cool idea. Mouse is something that gets damaged over time, and needs to be replaced... which is something you don't want to do with your computer. (Plus, your mouse will not be too comfortable to use when it has three cables that were not designed for bending, connected.)
