Query: Beware of Ergonomics

I only give it two stars because the laser tracking is magnificent! But the ergonomics of the mouse and the button placement make it un-usable. I tried this out for close to a week and was not satisfied. It left my hand cramped from even 15 minutes of use. It is too large in all directions and is very heavy, which required too much force to move the mouse. It would have been nice if the finger cutouts would be a little deepr for the pinkey finger and its counterpart and that the thumb print be shallower. The back and forward buttons strain your thumb to push becasue they are so akwardly places. The only thing to praise besides the laser is the scroll wheel. If they made a slimer version of this mouse, I would buy it. But until then, the mouse hunt continues.
