After looking at tons of bars to find one with gymnast standards, can hold more than a small childs weight, has leg extensions included, and at an affordable price, this was the winner. Unfortunatly safety was a major concern shortly after putting it together.The spring loaded knobs do not screw in all the way (pic 2) to securely hold the bar at the level desired. The pin itself barely makes it into the holes of the adjustable bar, 1/8-2/8th of an inch goes in (see pic 1, there are wear marks on the ends of the pins.) The bar fell many times on my daughters. Very scary since they are taller and could fall on their heads if hanging upside down. I had to use vice scrips to really reef down on both the spring loaded knobs and lock down knobs. This has helped it stay in place better but now is definitely not easy to adjust the height.A few other cons- some of the pieces had dings in the paint already. Not a huge issue. But when assembling, the product will scratch itself very easily making more dings in the paint. Assemble carefully. The leg extensions come with mini lock down knobs. The extension legs themselves do not have a hole drilled in hold them in place. One leg wiggles out often. And about once a week we need to tighten the screws holding the wooden bar-the screws provided are very short and loosen easily. (Oh, the wood bar did not come with predrilled holes which could be an issue for some people.)
