What a Great Product. The only difficulty I had really was finding the studs/joists in my garage to properly secure the thing. But that's my deal, not theirs. I used the 4 point lift system that's designed for a large canoe or small boat. But I'm using it for 2 kayaks. So the only thing I found not easy to set up was to level the cords' knots that are actually holding the boat straps up. It only took about a half hour to fine tune and has worked great since.
