I am very satisfied with my purchase. I am using it in a warehouse environment for both front and back doors and it is working as we hoped.
I would say for the money it's a great buy.

Perfect quality but a little bit weak

For the price, this is awsesome. Very easy to set up and get running. The remotes are sized so that I could use the same holes as my old doorbells and I like that I can easily slip off the remote from the base for battery replacement. Having the extra reciever allowed me to place one on each floor so i can always know if someone is at either door. I also liked the large selection of chimes and set mine up so that each door has its own chime.

Used it for my front and back doors. Volume is great and selection of chimes. Was so easy to install. Great Product....I would recommend it.

Works as good as any wired doorbell I have ever seen
