i bought one and ended up going back to my magic mouse. i use mostly magic mice, but i did finally figure out why i have such a strange mouse preference. it's the weight. so i bought a really lightweight razer mouse, and i enjoy using that.
it also charges on the bottom!
one thing i found that helps the size are these rubber bumpers you can stick onto the sides. somebody mentioned them to me, they're available on amazon and not expensive.
