This is a custom controller from Battle Beaver. Right stick: Z-Stick + 40% reduction Left stick: Standard Vibration off USB-C connection Two back buttons, one on each side Right: △ (Triangle) Left: × (Cross) This controller is customized based on the specifications of APEX pro gamer 4rufa. I purchased it as a new controller and used it once, but it didn't suit me, so I'm putting it up for sale.
