Ok, we have to be honest. This product is basic and not perfectly engineered…but it was easy to assemble and definitely feels safe. As for the assembly reviews that I read from others… I’m not sure if they’ve corrected all the issues or if I just got a good batch, but the I got two different sizes of bolts that perfectly matched the holes. I think a couple of lock washers were in order but I can add those for a few cents from the local hardware store. As for the ‘basic’ comment. The chain assembly makes no sense. I’ll use the chains to keep the rods with device, but the coder pins are plenty sufficient to keep the rods in place. I’m not messing with adding a ring on both sides every time. Also, the holes aren’t even drilled properly to use all three rods, but two feels safe and sufficient. Over all. I’m happy with the device. Of course my step ladder is 1” too wide so I do wish it was a little wider, but it’ll do. Assembled in ~10 min.
