The actual "bell" which is now where we need them and can hear. Either in the garden or cellar, just depending on where you are staying.
In the low price you can not go wrong. However, I wonder where you get the small battery that is built into the actual doorbell?
The batteries, which are installed in the actual signal generators include, not inclusive.
PS:
Now, however, I realized that always after a few weeks, the batteries are empty in Chime. And not just with me. My neighbor I bought same bell and with her same problem.
