Original PS4 controller, no defects whatsoever, but it has an opening that I've photographed. I honestly don't know the reason for it. I've had it for over a year and it has never malfunctioned. The reason for selling is that I have a second controller and don't need this one. Whoever wants to haggle, please don't bother. I've lowered the price for something I want to buy. Whoever wants to haggle, please don't bother.
