Title: Nice idea, but bad tracking
Review: I have the usb version of this mouse, and love it. Unfortunately, the bluetooth one doesn't have the sensitivity of the usb version, and skips and flies all over the screen. It's very fussy about what surface you use it on. Good thing it didn't cost a fortune to find this out though.
