I had my doubts before buying this, but after setting this thing up in just about a minute, I saw how awesome it actually is. Of course I did some tests to make sure that it could hold up my weight. I weigh 82kgs(180lbs) and it held me up, no problem. As long as you extend the bar out to tighten it, which was even easier than I thought it was going to be, it will hold you up. And, to my surprise there were some screws with little rubber knobs that you can use to put on the door framing to add extra support if you're worried. That being said, I didn't use them since I live in an apartment.
The foam that is used on the bar to hold onto is comfortable too, luckily, since holding up my own weight was a bit tougher than I remember.
Another thing is it's not invasive. I once had a different bar years ago that held onto the top framing of the door. With that you couldn't close your door and it was bulky. So it was kinda inconvenient to deal with. The bodyrox doesn't have that issue.
I haven't run into any problems with this product so far and I'm sure this product will hold up to the test of time, or should I say, it will pull up to the test of time (bad pun).
Hopefully, this helps any buyers when making their decision.
