The primary feature of the ZOWIE CELERITAS is the newly developed ZOWIE RTR™ (Real Time Response) technology which allows the user to define the repeat-response of their presses to be 1x, 2x, 4x or 8x of the normal repeat-response for a keyboard when using the PS/2 connector. RTR™ allows gamers to gain a higher responsiveness from their keys and thereby increase the pace of movement in FPS and Racing games or possibly even increase the APM in RTS. How fast do you like it to be? We give you the possibility so you can define your most comfortable repeat-response.
