After our Hausa Nage has given up the ghost, I was looking for a quick replacement for our 3-family house. In radio ringing I have always been skeptical about the reach, etc. I bought this product for all 3 families and all of them are actually happy. The furthest distance is approximately 15m - 20m through several walls. This distance creates this radio bell easily. I had to change batteries in the transmitter and receiver in a year time once. Now that a transmitter was stolen, I had to order a new set. The new model is in the transmitter a CR2032 coin cell battery and not as described, 2 batteries type Micro. That made it easier to screw a screw into the station for me, so this is connected to the base plate and can no longer be simply "clicked off". (More space in the stations with smaller battery)
