Love it! I read all the reviews before purchasing, and although most of the reviews were great, the odd one got me doubting whether this was a solid product or not. Now that I have received it and put it together, I love it. Take your time putting it together and hand tighten it lossley until you can line it up on the floor and make sure everything is squared before final tightening with the Allen wrench, then put the safety bar in. It moves a little when weight is not on it, but is totally solid when you put body weight on it. The vid in the review that shows a bolt not tightening, you'll notice he hasn't put the safety bar in, which has the thread that will actually make it tighten. So no worries on that. If you're a super big guy wanting to do handstands on the fully extended height, be aware that you are probably pushing it to the max, and if you're surprised it is not the most stable, well, duh. I'm a 5'7 female, and before I attempt to do a handstand on these bars four feet in the air, I might attache some straps to provide more stability, just in case, which is just a good fail safe, unless you have perfect balance. If I wanted to do a handstand and be wobbly AF, I would simply take off the exterior rubber caps to the feet and add an additional steel pipe, which I appreciate is easy to do. And I'd put it up against a wall if I was afraid of tipping forward or backward. In my opinion this is a solid design that you could further adapt if you wanted to push the parameters of its capacity. Bad reviews are; the product may have a manufacturer defect ( it can happen), but most likely people not knowing how to put it together right, probably due to using the Allen wrench right off the bat, which could cause the parts to tighten on uneven threads, and make it wobbly. So many options to choose from or spend more money on, I got mine, and was totally pleased that I chose this one. Relieved.
