Complete disapointment - SureFire M600U Ultra Scout Light LED Weapon

Used the light for one day with the remote momentary switch attached. Light got stuck on after a couple of hours of shooting. I disconnected and re-connected the switch and it fixed the problem, but only momentarily. Light got stuck on again later in the day. I called Surefire and was waiting for OVER AND HOUR before I ran out of patience and decided to do a return here instead of an exchange thru Surefire. Streamlight, here I come.
