Review on Wireless Doorbell Chime - AVANTEK Mini Waterproof, 1000 Feet Range, 52 Melodies & 5 Volume Levels With LED Flash by Justin Ewing

I get a regular FedX delivery that requires a signature. I can hear a knock on the door if I'm in the living room - otherwise I have to drive to a FedX store (in a pandemic) to get my delivery. This thing installed in a minute. The second receiver goes in the garage and I can hear it even if I'm outside. Loud enough (on high) to be annoying if anyone else rang this thing often. The only thing that takes any time to set up is working through all the silly sounds that are available (donkey, rooster etc) to get to the one that sounds like a doorbell. Very pleased. Should have done this years ago.
