I bought these to fix a drift problem I was having on one of my joysticks. After installing the replacement parts, it became apparent that these sticks were not accurate at all. Moving the wand just 10-20% in one direction was enough for those wands to think they were fully engaged. They could also be a D-Pad for the little analog control you have over them. They came with 4 so I tried the second one, same thing. With one of my other controllers, it was pretty obvious there was a problem.
