I've had 2 of these. They were wonderful, but they don't last.

I am using this mouse as I am writing these words... it is a good one but the major problem with it is the scrolling wheel that loses its traction and starts becomes loose and at times goes wayward! That is not good because otherwise the mouse it fine. Is there a way to fix it? I don't know. Logitech has better products out there and I am not sure if this one is one of them...

I have to take my comment back because I confused this model with another one. I had not checked my facts. Sorry. Therefore, do not pay attention to my comment about the scrolling wheel above (#2). Read reviews at amazon and elsewhere that might be far more helpful than my comment. Sorry!

#2/3: The scrolling wheel can be set in software. I had the same "problem" until I checked the settings.
Great rechargeable mouse!
