This is an awesome product! I had it up and running in a matter of minutes and got the hang of it almost immediately! It has totally took the place of my mouse and I like the 4x5 size. I think anything bigger would require to much hand movement for me.
I don't really like the feel of the mouse that comes along with it, but that's probably because I was so use to my older one. This isn't a problem because I don't really use the mouse and I still have my old one hooked up and ready to use if needed!
