The build quality is good, the torsional rigidity also ok. In the transverse direction, the castle is not appreciably after or barely play for free crowbars and similar thieves tool. The castle itself closes well and reliably and also shows after six weeks (eg on a car carrier) no rust or wear. The holder is practical and simple, it rattles nothing. The only drawback is that the holder depending on the position of the screws on the frame may be too high. In my context can the castle only slightly laterally in and out pulling and may scratch the frame. The problem I had not at the lower frame, but there must halt towards the Pulle :-)
All in all a cheap and good lock.
