ZOWIE FK1 and FK2 mice have been very popular among fans of ambidextrous shapes, but ZOWIE understands that nothing is perfect. This includes the shape of mice. 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. The new ZA series comes in three different sizes to give gamers more choice for different hand sizes and also people that prefer bigger or smaller form factors. ZA11 is the biggest, ZA13 is the smallest and ZA12 is in between.
