Coolermaster introduced 3 new mice: Reaper for the Aluminium series, Alcor and the Mizar. Reaper was evaluated previously.
Alcor is an optical mouse which uses Avago 3090 sensor and its as light as up to 120g with the cable and 86g without the cable. A lot of people would appreciate a very light mouse, some will not. A Logitech G400s weight without the cable is 118g, so those who have used MX518/G400/G400s can easily speculate how light the mouse really is.
