Hinges keep the not long

I had the hinges on our fridge-freezer (2 doors, 4 hinges) change there 3 times, the first time it was still under warranty, I had to fix it himself the other two times.
The hinges have a design flaw, the plastic part which leads the spring / limited breaks well from time to time and then no longer pulls the door to. In my view clear Geldmacherei with wear material / spare lines which are also beyond perverse expensive.

Ugh Siemens, Bosch, Neff, AEG, etc. so that a cheaper crap is already installed at the factory and is even sold as a spare part with a short lifespan.
