The ReFlex Remapping feature allows you to connect up to two extra back buttons. You can map any standard controller function (such as jump, reload, or melee) to these buttons on the fly within the programming mode without requiring any rewiring.

The kit offers thousands of possible combinations. Most features include adjustable Sub Modes, enabling you to fine-tune the speed and coordinate different functions to suit your gameplay style.

It provides deep customization settings allowing you to disable features you do not use or change how the LED notification indicators respond, personalizing the mod interface to your preference.
