Faulty mounting screw out of the box. windage adjustments don't stick. - iPROTEC Rail Mount Firearm Combo Light and Laser

Didn't even get this thing mounted and the screw snapped. Had my torque wrench set initially for 15 lbs since they don't provide any spec for that and it snapped before getting even close to snug. I have another one of their laser-only units and I had to put Loctite on the laser adjustment screws to prevent them from shifting around with every shot. As far as the light and laser, they were very bright with separate switches for each unlike some products. Great concept, failed implementation.
