The price of this wall box I felt at first as very expensive. But I personally had great concerns that similar products work really well. When I then struggled through me but to buy the product from Weibel, I was pleasantly surprised when opening the packet. This unit made a totally robust. No cheap Kunstoffscharniere. Easy to install. Good seal. A great concept. Absolute industry standard. Due to the high quality I have not paid the feeling too much. If the internally installed standoffs were still made of metal instead of plastic, I had absolutely nothing to complain about. I can recommend this with a clear conscience!
