The auction is for a near new rarely used Bluetooth Apple Mighty Mouse. It is still in the original box with the menu.

This wireless Mighty Mouse uses a laser sensor instead of an optical one. It also uses the Bluetooth protocol and does not require any sort of dock or dongle.

Features:
--Touch-sensitive top shell
--360 degree enabled clickable track ball
--Force-sensing side "squeeze" areas
--Laser tracking -- Laser mice provide the precision that need when dealing with pixel-sensitive projects in any software.
--Compatible with Macintosh, Windows and Linux PCs
--Programmable functions for the four "buttons"

It's powered by two AA batteries, but there is an interesting feature - it can operate with just one or two batteries (2 batteries included)
