Query: Poor Quality

Poor build quality. I never used it, so I have no idea if it would work better than it was manufactured. It had the following problems:1. The starting end of the male threads were a mess. They were distorted and chipped.2. The handle was not properly mounted on the shaft.I returned it. I'll buy something else from a store where I can see it before I purchase it.
