DieseRC DC 3.6V 5V 12V 24V 30V Wireless Remote Control Module 2A 1 Channel 433Mhz Radio Control Receiver Module with 2 Transmitters Small Mini Size Controller

I didn't install these receivers yet, but I tested them and they work well. Exactly I need for my project.

Works great once I used a power supply with enough wattage. The power gets divided between the receiver and the LED driver circuit.

I have some outdoor lanterns powered by 3 AA batteries, and getting to them to physically turn them on and off was a pain. These little devices were easy to splice into the wiring between the battery leads and the LED. Now I can turn the lanterns on and off with the click of a button. My only challenge was pushing a tiny button 8 times to clear the remote pairing so I could reprogram one to control two lanterns with one button, but I succeeded after a couple of tries. No problem operating them from a distance of about 30 feet. Overall they are perfect for my needs.

Decent product at a good price..

I am impressed at how small this is. Equally impressed at how well it works. I've connected mine to a 12VDC power source, and the other end is connected to a small solenoid. I haven't pushed it to its limits, but it works great from 40'. This has four modes: momentary, toggle, latched, and delay, which allows me to tailor this to my needs. Very happy with it.

I used these and a buck converter to set pins on an esp32 board to be high or low in order to issue commands wirelessly. Tested at about 100ft, haven't tried to max out the range since it worked within my project range. Satisfied customer.

Product states it is good for multiple voltages and 2Amps. It was placed in a 12V 2A circuit and immediately failed.

I wanted to use this in latched mode (on and off) and I could not get it to set up. I followed instructions and got it to the point on setup of setting the on button but it would not set the off button. It did the flash for on but then instead of bringing up the red to set the off key it didn’t do it and just ended the setup. So I went back and was able to set the on/off on the on key. I should have returned it, but this is the third one of these and this is the only one that partially worked. I just was running out of time.
