The wall installation works without problems, but:
Disposed of the plugs most directly. The description is given that you should install the pull-up bar at least with the supplied 12er dowels / propeller combination. I have unfortunately only tried. The supplied dowels lie somewhere between a 8-and 10 plugs. The dowels have too much play, even in a 10 hole and turn the screw. The screws holding but bombproof in commercial 12er Fischer dowels.
The product is with "professional pullup bar" offered here, but the product itself is provided with a label "Home Edition". The only as a side note, I think it is clear to what can be expected for around 33 euros.
