ExtremeOCTech posted a review on the Logitech G5 Gaming Mouse V2

The Logitech G5 v2 is amazing. It seems much more durable, sturdier, yet maintains the accuracy of a precision mouse. I highly recommend this mouse for any FPS gamers and Graphic editors who need accuracy and precision. For gamers the on-the-fly resolution changes will come in handy during changing scenarios in-game.
