After a quick delivery, I could unpack a really great door chime. The station I immediately fitted with batery and plugged the receiver into the outlet, already could be rung. From the large sortiment of melodies sure to find something for themselves. The volume is sufficient. The second, with batery powered receiver, has an enormous range, so we can use it in the garden behind the house. It's also nice the optical signal that flashes in time with the melody. Price performance unbeatable !!!
