It is very difficult and not nice for the furniture to find the exact mounting position. If you are too far away from the hinge, the door is pushed open. Too close to the hinge ==> no damping effect. To make matters worse, that the mirgelieferten screws have a small head and thereby to fit easily through the holes of the door damper. I keep them in order to determine in a quiet moment on my test unit the optimum position.
