The clamps are very robust and very well hold in the wall. The nails are also very good. This does not bend.
The clamps act definitively High quality and not just processed cheaply.
For this money, you can not expect much, because you simply no better clamps gets for this unbeatable price !!
Even the cables are slightly thicker, you can fix any problems with these clamps, as these clamps also something "wide".
Prima!
For me, a strong buy recommendation. You can go wrong with these clamps definitely not !!!
