My ProTac, after being ran over by a loaded semi, (roughly 76,000lbs gross). Dropped the light, when opening the trailer doors, didn’t realize it. Jumped in the cab and backed into the dock. Dropped the trailer and pulled the tractor forward, went to install the kingpin lock and saw it laying on the ground, directly in the path of the tires. Took it like it was nothing. Works perfectly fine. The best flashlight I’ve owned, hands down.
