Castor is one of the latest Mionix mice which integrates the PWM-3310 optical sensor for a DPI up to 10000 and a powerful 32-bit ARM processor which runs at 32MHz with 128Kb of built-in memory for recording macros but also for storing up to five profiles. After several hours of use during gaming (ZOMBI, Killing Floor 2, Cradle, Wolfenstein Old Blood, Guild Wars II) and office work, we have concluded that the mouse performs admirably and remains very comfortable thanks to its shape; versus ambidextrous mice which also have buttons on the right side, Castor has an area dedicated for resting your pinky finger so right-handers will be happy with it.
