Signal transmission OK, mechanical design not the angle plug

I use the cable to my cable Germany to combine my FRITZ! Box 6490 connection. The socket of the cable connection on the wall behind the bed and a normal plug was a bit too far out of the can and was strong abknickgefährdet if you accidentally moved the sofa. So I wanted a cable with F-angle plug. And what I wanted to buy sturdy, is indeed still a bit off the wall out and is still easy sofa at risk, so rather pay 11.49 and not take the allerbilligste cable Kunstoffwinkelstecker.

The cable works fine for the purpose and the signal comes in good quality (at least sufficient for up to 200 Mbit / s downstream) on my FRITZ! Box. So far so good. Now the angle plug.

The angle connector actually makes a very robust mechanical impression, everything from metal, feels heavy, etc. When screwing on the F socket on the wall, however broke while tightening the screw (only by hand tightened, etc. no tongs used) after a few rotations of the cube-shaped rear part of the connector of the front part with the screw. It was seen a gap of a few millimeters. I then quickly put the dice back in the ring. It rested also felt again a bit. The cable is still working, but this experience tarnished my impression of the robustness of the plug significantly, therefore only 2 stars.
