These controllers are well built; a near-perfect replica of the original xb360 controller. However, I wanted to replace the controllers that would work with the existing controllers and existing original xb360 receiver (for PC). Contrary to what the description might suggest, they will NOT work with existing receivers. You can operate multiple devices at the same time, but each must have its own receiver. And then they all light up as #1, making multiple lights useless for 1-4 players. Multiple devices fail to pair with one of the included receivers even though the controller has a pairing button (but not the receiver). Return to another manufacturer's controller for the same price that does not include the receiver but pairs multiple devices with the original xb360 receiver and lights up 1-4 at a time.
