This led to the following problem. I had ordered a 4-fold shielded cable with 7mm diameter. This was already screwed with some trouble on the high quality plug. On the Hama plug that was not possible without editing before the cable. Even a "pre-cutting the thread" with the high-quality connector was no use. With a little skill you can solve the problem but. For cables with smaller diameter I see no problems. After the Hama plug function as they should. The cases sit tight and hold on tight.
All in all a simple product at a fair price.
