Reaction times are ulra-fast & responsive for quicker double & triple taps. The action is predictable & linear unlike lesser gaming keyboards that have a tactile bump or the annoying click of a typists keyboard. **18 dedicated, customizable G-Keys** Easily access to your most frequently used macros, presets & key combinations even during the most intense action. You can record up to 54 programmable functions accessible from three separate banks, ideal for grouping macros by function, or access. Macros can be created on-the-fly, customized, & activated with a single keystroke. ** Full key matrix anti-ghosting** Our expertly designed anti-ghosting technology provides flawless control even when youre pressing multiple keys at once.
