Great
So cool being able to max out a machine and continue adding weight. Very sturdy. Highly recommend

My son wanted it for his birthday and is happy with it. The company went out of their way to help with a shipping cost issue and I greatly appreciated that!

Solid gympin, would recommend
It’s a pretty solid piece of equipment, to this point it hasn’t shown any major flaws, the only small flaws are that the pin itself does bend a little when under heavy load for a long time but not enough to be a problem and that the Kingpin isn’t as long as I hoped. In general I’d say it’s a good tool for overloading gym machines but it’s price might be a little too steep. In conclusion, I would recommend it for people who are willing to pay the high price.
