The Mad Catz C.A.T. 17 is a customisable ergonomic controller built around genuine Hall Effect sensors on both the analog sticks and the triggers, meaning it uses magnetic sensing rather than physical contact wear points — the same underlying technology prized in high-end controllers specifically because it eliminates stick drift and keeps trigger actuation consistent over years of use, rather than degrading like a traditional potentiometer stick. Trigger actuation is adjustable across three levels, letting a player fine-tune how much travel a trigger needs before it registers, and its D-pad and joystick functions can be swapped along with customisable dual vibration strength, all managed in real time through the companion KeyLinker app alongside macro-enabled buttons. Connectivity covers both wired and Bluetooth, switching seamlessly between platforms, with roughly 16 feet of wireless range and USB-C charging; a single charge is rated for up to 20 hours of continuous play. It supports iOS, Android, Nintendo Switch, and Windows, making it a genuinely multi-platform controller rather than one tied to a single ecosystem. It includes RGB lighting, measures 6.07 x 2.85 x 4.37 inches, weighs 0.79 lb, and carries a 2-year warranty on parts.
