Excerpt: I wasn't entirely sure about this mouse since it looked at bit small, but I decided to give it a try. It is indeed a full sized mouse. I have rather large hands with long fingers and this is a perfect fit! The setup with my Mac was a matter of popping in the batteries and about ten seconds for my Mac to recognize it and it was ready to use. The tracking is a bit fast so I had to set it to the slowest option, but it now works like a dream!
