Logitech MX500, MX700, MX1000, G5
Razer Naga, Naga Molten, Naga Epic
None of the mice can keep up with the G602. The battery life is terrific. With a battery keeps the mouse in the Performance mode loosely by 150 hours. The weight is okay, but that's what you have to take with a wireless mouse in purchasing.
The driver is working properly and the precision is very good. At the, where 2500 dpi are not sufficient. I bet every matter that you can not move to 1/100 mm exactly his hand.
I put the mouse on a hard plastic, wood and lacquered wood. The sensor can handle all three surfaces.
Strong buy recommendation, especially at this price.
