If you're looking to replace your old bare sticks, this isn't the solution. If you buy these and install them on a used controller, they will fall off after an Overwatch match. They were actually designed to be used with a new controller. There are 3 anchors on the underside of these control freaks that flex under the thumb you place them on. Two slide on the right side while one bends the edge of the rubber ring to hold it in place, but that part stays bent even if you remove it, so be aware. Are they doing their jobs? Yes, and it will, I immediately noticed a difference on the right joystick which is high travel. This will add some depth and space to your aiming.
