The ZA12 by Zowie Gear uses an Optical sensor from Avago, specifically the 3310, providing a DPI/CPI range of 400 / 800 / 1600 / 3200 DPI.. It uses a USB connection. The ZA12 is considered to be an ambidextrous mouse. It weighs in at 85g without the cable and is approximately 124 x 64 x 39 mm (LxWxH).
ZA series comes as an answer for the gamers who want to rest their palms on the mouse and those looking for a mouse which is easier to lift with a claw grip. In stark contrast with the FK series, the new ZA series has increased height on the back of the mouse to cater for people who like ambidextrous mice but want to be able to rest their palm comfortably on top of their mouse.
