My current bell was only audible in the kitchen. This wireless doorbell is amazing. Volume can be turned way up if you are hearing impaired. Grandkids love to cycle through the 50 sound selections. Several traditional bell sounds, rest are songs, nature, and animal sounds. With two receivers that plug into a regular electric socket, I can hear when the bell rings both upstairs and downstairs. Bell/transmitter was easy to install. Screws were used. It is partially shielded by the back door, so not sure about waterproof properties. It has rained a few times and so far so good. Great product for the price.
