This is pretty much the be-all-end-all of gaming mice. New in box, unopened. Wireless with a custom receiver (more precise and better reliability than bluetooth), capable of wireless charging while still in use for a true cordless gaming experience.
Retails for $199+tax at bestbuy.
I fell in love with the slightly cheaper Pro-G version, and this one is now surplus. My loss is your gain.
Price firm.
