Not happy with the quality of the sheathing around the set screw, after struggling to get the bushings into place I finally got it done and the last thing I have to do is tighten the set screw and after a couple of careful wrench turns the case around the screw cracked, and now the integrity of the regulator is broken. I know I didn't over tighten the screw because I didn't have much leverage to turn the screw. Not satisfied with the quality and the fact that you have to buy another one and try everything again.
