I have been using an Anker vertical mouse for about a year now. It's far from feature rich, but the build quality is impressive for a $20 mouse, and it's very comfortable. AAA battery life is good-great (it's not rechargable). I have medium-large hands for a male, and it sits in my hand great. As you get used to it, you do have to be careful you don't send it sailing across your desk when you go to reach for it! http://a.co/dw6aVMO http://a.co/dw6aVMO
