I say read the 1-2 stars on this first as there a lot, I wish I did. THE selling point for me with this was the RECHARGEABLE battery "built in" (its not its just a rechargeable AA battery).Ok this thing is HUGE too, not good for the smaller hands out there.It really doesn't hold a charge as long it could or should.  My M510 mouse which uses alkaline, hasn't had a dead battery in over a year.This MX mouse, requires charging once a month at least.  Not good.  Anyhoo, save yourself 60 beans and get the M510 instead.Yes too the scroll button is like a out of control spin wheel, not accurate like most that click/stop per spin. 

Question: How is the review?
