On radio ringing we have now by so few, beginning with the cheap Aldi and Lidl finally landed (in the exact order) on a from the hardware store, we are at this. The first three products have unfortunately very quickly given up the ghost, either due to moisture from rain or cold in winter they had done himself. Can you really save is equal, which are simply bad. Then we browsed at Amazon and also read a lot of reviews and ended up with this model. And now we are thrilled. We use it for 6 months and are more than satisfied. The installation was easy and went very quickly, the workmanship is very good and also has an attractive design. The scope of delivery is super because everything is thought of. And the best part: It works without any problems, even in the rain and cold! Great product!
