The Asus ROG Keris Wireless Aimpoint is a very successful mouse model. The SpeedNova wireless is among the fastest systems I've encountered, and the Aimpoint sensor worked without hiccups. At 75 grams I consider it perfect for me, and the shape lends itself well to the Claw Grip. The battery lasts a minimum of a week. Could have the DPI switch positioned better, maybe on future versions.
