Review on 🔌 Solidremote Wireless Relay Switch Kit-1: 2-Channel 433MHz Receiver with 2 FCC ID Transmitters for Garage Door Openers, Cars, LED Lights & More - 12V-24V Universal Solution by Adam Price

Works very well to spruce up an old (20+ year old) Craftsman garage door opener. The RF receiver failed and I used a second receiver from a big store but it just didn't have enough range. I thought what the heck and replaced it with this one. It was easy to set up and program the remotes. All I had to do was power the unit with 12V DC and connect two wires from the garage to the unit using the NC connectors. One of the remote controls has battery discharge problems. I've cycled through 3 batteries on one remote and the other is still on the factory battery. I deduct a star for that.
