As a Counter-Strike player and professionally on the PC working person I can only say: "Man, I'm glad to have this mouse." I can confirm that this mouse is the most accurate and fastest that I have ever used. They responded extremely well on minimal movements and also with quick actions she has no problems, mainly the Aiming comes in FPS games to Good. Problems that the mouse would verreißen etc., I have never experienced so far. She works generally very reliable. Any inaccuracies and drop outs are anyway not due to the mouse, but the driver, however, is still in its infancy. The shape and design of the Dual Optical are top notch. It lies perfectly in your hand and with its three buttons and the mouse wheel can they prove tidy. How much light emit optical sensors, it can be seen when you're sitting in a darkened room in front of the PC (my desktop appears solid red). I may make a crystal clear buy recommendation.
