These things save lives. We had a classic derailleur problem: the factory controls slipped on the derailleur when used. These aftermarkets are for solid! I love the feel of them and the light and vibration work really well. You can use the factory controller covers on it even if they are not connected to the system. They are also perfect for 4 players on TV. The only downside is that they don't fit controller accessories like handwheels or handheld gamers.
