Ah! Sweetness. I don't think the difference between laser and optical is as big as going from trackball to optical. And then MS just came out with that bluetrack stuff...

These are starting to look more and more like Logitech's mice.

how can you get "6+ Months Battery Life on a single AA battery", when the device "Require 2 AA batteries"

#3 - maybe it is like my Logitech wireless mouse. It holds two batteries, but it will run on one. If this thing performs like mostb other Microsoft wireless mice, you will need the receiver about one inch away from the mouse.

I have this mouse. It takes a single AA battery and works fine, no troubles with needing to be right next to the receiver.

A mouse is a mouse is a mouse...this one's comfortable and I like it. Batteries last a few months...kind of a pain when they die before a presentation but that's the risk of wireless.

get the logitech mouse. way better!

Receiver is way too big. Kensington and Logitech have shrunken them down so small you barely notice them. Or go bluetooth.

hey, but for $15, what more can you ask?
this is one of the better deal around this time already

Logitech makes better mice imo.

Got this Black Friday at Staples for $13. Really like it. Fits hand better, works great. Best thing for me is the audible click. Some may want silent operation. I never would have thought to want an audible click but for some reason it helps me a lot.
