I have a G500 mouse that I recently bought. I used it for about 8 hours too see how I liked it. I liked the feel and weight, but I'm selling it and sticking with my G700 because it has more buttons. I put it back into the box and it is in new condition.
Includes everything that originally came with it - manuals, driver cd, weights, etc.
$40 PayPalled and Shipped.
Date at the bottom, blurry, but look close.
