Input:
I just have to jump in with everyone else and say this is the best mouse out there.  It literally saves you room on your desk because you don't have to move the mouse controller anywhere.  The entire device is a natural fit for your hand.  Buttons are great and easy to find and click on.

Used up my first one completely - and then some.  I didn't want to part with it and I didn't want to have to hunt for another one. I knew I couldn't find one at a big box store - they just want to sell you all their wireless stuff.

Going to pick up another one from Amazon pretty soon because the price is good and I'm using Prime now to get everything shipped to me ASAP.
