Just installed this on our home. Easy to mount and set up. Quite a selection of ring tones. If it lasts, it will be worth its price and more.

This was easy to install and works great! When the transmitter stopped working customer service was excellent! Within the week I had a new transmitter. I would recommend this product as good value and easy to install.

This is very easy to set up . I put at my back doors of the house, since they have to regular door bells. that work great and you can hear them from the front of the house.

We liked it so much we recommended it to my parents and they bought one, too! So nice to have the color choices - ours is black and theirs is brown - so we could easily match the exterior of our homes. Thanks for a great product! I'll refer it over and over.
