This mouse is tiny. If you have medium or large hands, take a look at the measurements of this mouse. It's wide enough, but it's such a flat mouse that I can't comfortably put any part of my palm on the mouse without bending my fingers an uncomfortable amount.
Build quality is excellent, the buttons are clicky and give great feedback, not mushy at all. The mouse is light, but solid. Nothing shakes or rattles when I shake the mouse. The coating is awesome for sweaty hands, as you sweat you get more grip.
If you use just fingertips, or have smaller hands I would definitely recommend this mouse.
