In reply to j_duds: I've got one, as has a mate.
In general, they're pretty good, however;
o My friend uses his more intensively than mine, and the bar that braces across the doorway (at the bottom) is wearing a groove in his door frame.
o I live in a new build, so hollow walls&plasterboard, and the 2 brackets that "hang" onto the top of the frame have pushed into the wall and left 2 holes. This may/may not be due to the door closing when the bar was in place; I never worked it out.
I now have mine spanning the rafters above my loft hatch, but they seem to be fairly decent bits of kit for light use or solid walls/frames.
