Use at your own risk. I came off the stands and slipped off the step and felt about 8ft and they didn't catch. Luckily I wasn't hurt, but it could have been bad. What struck me when I received it was that the rosehip knots seem questionable given the material they are made of. They are very tightly woven cords - almost like paracord - and they don't work properly to grab the cord. You will find that they slide too freely. They don't create enough friction to actually lock up the way they were designed. If you climb a tree with them, they actually slide down. I thought that maybe with a sudden jerk when they fell, they would actually grab it, but they definitely didn't. They will follow you right down the tree. I don't understand how a company like Muddy would sell something like that. They must be taken off the shelves immediately before anyone is killed.
