Unfortunately I had to notice that the bell with me did not work, so I've disassembled completely and had a cable that ran to the receiver in selfmade work solder because it is demolished. If it does not work then I would have returned it. Up to that
With this bell I was not satisfied. This part is very large, and the quality has not convinced me. At Aldi I later found for half the price of a much higher quality wireless doorbell.
Good melody selection, beautiful sound and supplied with double-sided tape simply and securely mounted on the outside wall. Receiver is processed fairly dibasic.
