Review: Very Happy - Excellent product very happy
Review: I agree with others that this product is garbage and a waste of time for all, including Powertec. The problem is they are impossible to tighten without stripping the allen screw. Anyone who 'tests' these will see it is obvious the relief cut is too shallow on the color and no way to have them tighten. I can assume the larger one may work but 1/4" did not. They deserve the returns as they do not seem to be listening to customer feedback. Maybe they are just trying to dump bad inventory.
