Enough gekrittelt. Because the bell does exactly what it should. And that better than my normal bell whose volume I can not change and can not be disabled. The receiver is discreetly chic and therefore does not interfere in the socket. The range I can not make fullest. The normal "Ding-Dong" sounds to me actually very pleasant. And everyone else - not only children - has a lot of fun because secretly set me a funny melody as possible. The service - ie adjusting the volume in three stages and the selection of the tune - could not be easier.
I find it quite as comfortable win to have a bell that can follow a in the basement, on the terrace or sometimes while vacuuming from room to room.
