Bests & Worsts Reviews from Amazon

I ordered this mouse since I have been working 60 hour weeks as a software engineer and my wrists (and mostly my right mouse hand) have been killing me and I thought this may help. Well, I took it out and the first time I tried to scroll down a page, I realized there was no obvious way to disable that annoying notchy clicky scroll function. (i.e. no free scroll) After some research, I found that this was by Logitech's design. I have had dozens of Logitech mice, and EVERYONE of them had the free scroll option, but not this $100 piece of junk. After a couple of hours I Really began to hate it. It was awkward, felt plasticy and cheap, was not very precise, large clunky and worst of all, it made my whole wrists and arm sore. I am returning it and that will be the last Logitech mouse I try until they bring back the quality that I had learned to expect from them...
