You’ve probably seen musical doorbells before. The MDB-2 Musical Doorbell is like most other ones with 100 built-in songs and sounds. But this doorbell has one unique trick up it’s sleeve- a little piano keyboard to program your own songs! The sky’s the limit, whatever song you want, you program it in (even if the only song you know is “heart and soul”). You could always look it up, the keys are labeled.
