If you ever find yourself with the opportunity to buy this item… Don't. The instructions were predictably stupid and impossible to follow (attach unit A to Unit D, using 24, 26 and 27…all while nothing is labeled and the manual looks to be drawn by a small child with Parkinson's…wording so small that my glasses needed glasses to see it).
Once you make it past that… then you'll see just how low quality this fabulous item really is. You'd likely be safer to simply hang yourself from your ankles off the side of a moving airplane and hope for the best. I used proper tools (not the crackhead crap they send) and at its tightest and most secure, the entire thing is wobbly.
If you're brave enough to try it… you'll absolutely throw your back out and tear muscles while trying to flip yourself backward. The balancing is… off. …but… it does come with some janky straps with plastic clips, all held in place on about 1.5mm of bolt. So… that's good. You might not actually fall out of it. It's likely gonna collapse, but you'll remain strapped in.
Once you do flip yourself to an inverted state…constantly thinking about the possibility of being stuck like that forever or the platform snapping in two and you landing on your head will 100% stop you from thinking about those insignificant aches and pains that lead you to buy the table in the first place. So… that's a bonus.
I rated it with all single stars because negative stars wasn't an option.
