Review on SadoTech'S Wireless Doorbell Kit: 1000-Ft Range, Waterproof And Loaded With 52 Chimes And LED Lights by Matthew Augustin

I live in a house built in 1957 and sure enough the front door bell stopped working. I checked the bell itself and that worked when I tested it off of the wall with a power supply. Checked button it to worked. Checked the transformer and again it was working correctly. So at this point I did not want to dig apart walls to chase the wire as it goes from the front door to the transformer in the attic of all places. (Why was it there?) Who knows but bad idea, anyway I ordered this door bell system got it in 2 days took it out of the box plugged in the receivers pushed the button and what do you know I heard DING DONG. And the Ding Dong sound sounded pretty much like a bell not some electronic beep sound. There are many tones but hey I am old fashioned I just left it set to the ding dong. It came with the 2 receivers and 2 buttons great range and you just plug the receivers into an outlet no configuring needed. I recommend this system to anybody
