What system is it for, if its for Xbox PS2 or any console video game systems, i highly recommend not buying 3rd party controllers due to their poor response
There r no OEM wireless contrllers for Xbox or PS2. Gamebird is the best out there. Right now, I too have the Logitech for Xbox and a MadCatz for PS2. So far so good.
Did you try the Connect button on the reciever? Also try unplugging and replugging the reciever. I just picked up this controler a couple weeks ago and had mine kick off once. Used the 'unplug' solution here.
