Awesome little mouse. Have one and am using it right now.
It has 5 buttons (scroll wheel is middle + 2 near the thumb, made for righties). Scroll wheel does up/down, left/right.
It takes 2xAAs (works with my Eneloops, this may or may not be due to the glitter ;).
$25 delivered, normally $40.
Ordered one - here is hopping is is better than the two (crap) generic ones I've purchased before!
