What buyers say about the Add-on receiver
5 out of 5
I’m very pleased with this product although I live in a very small house it’s always been difficult to hear the doorbell now I can hear it even when I’m downstairs as I was able to buy an extra receiver, definitely worth the money

I bought the SECRUI Wireless Doorbell set. 2 buttons one receiver. works amazingly well, but I live in a 2 story house.so I got the second receiver for the upstairs. that made all the difference in the world. now I can hear it no matter where I am in the house. pairing it to the original set was very easy.
