I bought this very favorable set tentatively. In my house I had a very expensive designer wireless doorbell system installed. Unfortunately, the bell was too low and the batteries always empty. After I had assembled this small set (actually is nothing to install), the ring never ignored. A station in Erdgechoß in the socket, the mobile part I have upstairs in my studio because I am staying mostly there. The bell just stuck. That was everything works properly is practical, I am thrilled and can only recommend this set.
