Very well built! Very strong and sturdy. Overall happy with this product! Although I did not receive an email with instructions to put it together like I was suppose to, at least I was able to google the instructions. I'm not a fan of twisting the pins to adjust height but that is probably because I'm use to a different way if doing it.

We have had the again faster 4x4 rig for a few months now and wouldn't go any other route! It's more solid than most gym's rigs in town!
