I ordered 2 copies, one for me and one for a friend, and each represents a new Weber gas grill. However, with the thread there were problems. We got the knob barely on the connection. The threaded screw was not so easy. Despite relatively high use of force, the thread was ultimately not completely screwed. The gas sample showed that gas escaped - and that may now not happen again. So the governor went back to Amazon and then had to but the original controller from Weber to buy. Thus, there was no trouble; simply screw and you're done. Save at this critical point can then optionally but are dangerous!
