Set screws were loose. Couldn't find an Allen key that would fit (metric or standard) from 2 different full sets of wrenches. Whoever processed them must have worked on the first day and just barely passed the quality control. I bought some set screws at my local hardware store and was able to replace them quickly. As for the price, not surprised I had to play around with it. This is a cheap stinger grip. This will keep me going until I have the time and money to find a suitable replacement for
