Everything USB published a Logitech G700 Wireless Gaming Mouse Review.
Quote from that review: "The Verdict: The Logitech G700 gaming mouse is one amazingly powerful mouse, which is as easy and comfortable to use as it looks! Power, performance, looks, comfort, programmable buttons. This mouse has it all. Highly recommended if you are serious about gaming.
Comfortable yet elegant design
Works over wireless or wired mode
Small USB transceiver
Dongle supports up to 6 devices at once
13 programmable buttons
Refined and user friendly software
Quick connect charging cable means a dead battery never means you have to stop gaming!
Integrated holder for the transceiver
Uses a single easily replaceable AA rechargeable battery
Battery can be charged while still in the mouse (just plug in the USB cable)!
Right hand only model
No weight customization
A tad too heavy for some
Software CD not included
Included AA battery is only a 2000mAh
Charging cable is not braided and is tad too rigid
While it technically has 13 buttons, one is more less dedicated to the scroll wheel control (ratchet vs. smooth)"
