The Roccat Nyth is wildly customizable, with over 18,000 different button layouts. Included in the package is a set of extra buttons that magnetically attach to the side of the mouse according to your unique preference. It even comes with a swappable side grip to accommodate both claw- and palm-grip styles. For even more customization, the Easy Shift key lets you assign a secondary function to each individual button, which effectively makes the mouse capable of up to 1024 combinations.
