Absolutely terrible. I don't think I've ever written a review before but this one is so bad I had to. Crimping doesn't hold, tightens with minimal effort. The heat shrink tubing hangs over the end of the bushings so it needs to be cut off. Because of the way the heat shrink tubing is applied to the tubing, it's hard to tell where to crimp. Complete rubbish, I'll never skimp on it again
