I've bought the doorbell despite some poor reviews. This was an absolute gem. The price performance ratio, and the doorbell keeps its promises. I live in a house with 4 floors, and inhabit the attic. So I was a bit skeptical beforehand whether the door chime the crow flies from about 15 - accomplished 20Metern by several doors and walls. But surprisingly, he does this to my complete satisfaction. He is not disturbed by the many wireless routers in the home. Therefore, I can only rate this door chime with 5 stars, because it is worth the money of the reach really.
The only negative thing you would have to say, and what also often came through in some reviews, is the melody of ringtones. I must say that I could imagine as a doorbell anyway "Jingle Bells" or anything else. But the sounds of the most jingles sound simply wrong. This is particularly unpleasant when one expects of his musical bell claim. However, I did not make this claim, and there is also normal "Ding Dong" Jingles with whom I can live very well.
