I've confirmed functionality using a gamepad tester. Drift values are within 0.1. There were no issues, but please understand that this is a basic check and the item is used, so it's being sold as junk. I have checked it, but please refrain from purchasing if you are overly concerned. I have not disassembled or repaired it. - Model: DualShock 4 - Color: Black - Brand: SONY - Type: Wireless Controller Thank you for viewing.
