Oh, ye of little faith. I can strip the head on a flat-head screw. I just stripped the hexagonal indent for an Allen Wrench on something.The buzz screw is flat-head, not phillips.. so no worries about stripping it.
But, if the same thing worked for everyone, there would be only one PV model and one flavor of liquid.

Its ugly, and I am not pleased with the button, I watched video
