Review on RF Remote Control Switch EMylo Smart Wireless Relay AC 110-240V 2000W 1 Channel Momentary 433MHz Module With 2 Transmitters by Alexander Roberson

good product. Does what it is made for. I mounted the push button by the door. Now we can have lights when we come in. the negative part was the terminal block wire slots were so close together I couldn't use 16ga. stranded. I had to use 18ga. solid to keep the wires from touching each other. So the 4 star rating. the system gives me remote control of the lights. Much brighter than expected!The picture show hooking a positive wire to a negative, I knew that would be a dead short. I figured it out.
