Great piece of equipment. It is extremely durable and I will use it for years to come.
I was very excited when I found this on the internet, but after receiving it and trying it, I could not get it to level out on all four legs. No matter where I placed it or what level I would put it at, one side would be off the floor. When you are doing box squats, you want a solid base to sit on. I rectified the situation by wrapping duct tape around the one rubber foot that seemed to always be in the air. After several wraps, it evened out the rubber feet and now it doesn't rock. The bolt holes or welds were incorrect on this particular box. I love the concept and will continue to use it.
Sturdy construction, affordable, and absolutely fun to use! Variable heights allow both me and spouse to use the same equipment after a height switch. The safety mechanism is great! 220lb spouse jumps with 100% confidence even with a weight vest! The quick free shipping made it possible to enjoy this in under three days. This piece of equipment is versatile and won't disappoint. I am petite and not brawny at all and was still and to adjust the positions myself.
I was very impressed with the quality/price ratio on this item. It functions exactly as it should, is very well made, and with free shipping? It's a no-brainer!
