DieseRC 3pcs Relay Receivers with 2 Transmitters 433Mhz Wireless Remote Control Switch Radio Frequency DC 12V 1 Channel Passive Output Relay Controller

I'm using this to control a dump trailer that has Power up and Down and also a Gravity button so this 3 button remote worked out perfect. So far it has worked good, only wish it had an external antenna option as range get's fuzzy as it's mounted inside a metal box on trailer and metal and RF signal don't do to well but other then slight distance issue it still works as intended.

I needed an easy to use remote switch to control some solar powered lighting in my yard. The remote easily worked from 100' feet away. Now I can light the yard and keep an eye out on my dog.

I used this to add remote start , remote tilt and trim to my boat so I can raise the outboard as I was pulling away from the ramp. Product works great and I will definitely buy these for another project

Inexpensive reliable decent Range and easy to set up.

We have old industrial garage door opener that has open close and stop bottons. The opener has radio receiver block with 3 ports for wires, R1(n.o., normally open) R2(-) and R3(+). I wish the instructions helped better for this situation. On the reciever i put 2 wires into the negative port, one went to the common port in the reciever, the 2nd wire went to R2(-) on opener. 1 wire went from (+) on reciever to(+) on opener. Final wire went to the normal open port(no) and went to R1 on opener. It works as a single button to open and close garage

Very nice tester

The one that worked was great but disappointing to have two of them not work.
