After I had compared several pull-up bars, I ended up in this, they have ordered me and am more than satisfied. The bar holds bombproof in the doorway, without any screws. The great advantage I see in this bar is that it goes diagonally through its construction method nor the actual door frame and the rod is thus in a proper height. Much legs must be no longer bend it.
A great tool you when not in use can also easily stowed again. I am completely thrilled, 100% buy recommendation!
