Review on 🔧 eBoot T8 and T6 Screwdriver with Electronics Prying Tool - Perfect for Xbox One, Xbox 360 Controller, and PS3 by Nadine Glaser

They worked great on my new Xbox One controllers but this set doesn't work on older models closer to system release. If you have a newer controller with some twitches, you can hack it and fix the problem. If you have older controllers, the drivers will not fit on some of the internal screws. The attached photos show the difference between the controllers. Works on my blue but not black.
