If you've already disassembled the controller to replace the joysticks, then installing this mod shouldn't be difficult. I immediately noticed the additional and nice weight in the controller. The first octagonal metal button I received had a manufacturing defect, a small metal burr preventing it from sitting straight, but TOMSIN's top notch customer service team came IMMEDIATELY and sent me a replacement that works beautifully (the standard D- button also feels and works great). Thanks TOMSIN for your help, you won my future pho sho business!
