The bell was delivered very quickly, contrary to other reviews as well the appropriate battery was settled. Quick assembled and installed. Became now for a week in service, everything was perfect. The bell has a path of about 10 meters and two basement walls overcome - works fine. I had some other radio ringing in use that the spirit hope aufgaben.Ich usually after one year, they will last longer. The design is spectacular, but that does not bother me. The choice of ring tones is large, but not necessarily tasty and useful. For me, it fits, the simple double Gong ranges. From me: clear recommendation.
