433Mhz Universal Wireless Remote Control Switch DC 12V 1CH Relay Receiver Module RF Transmitter (2 Transmitters 2 Button+ 1 Receiver 1CH)

Has been working well, range is very good comparatively to what I was excepting (70feet?). It was straightforward to install for someone who understands circuits and electrical diagrams. I would not have been able myself alone, the instructions are not newbie friendly.

My 1st time using a remote switch, very easy to install, did a mock up and then the permanent install, directions are good , just follow what the pictures have , my setup i had to run one jumper wire from the positive to the com and it works like a charm , button A to turn on , button B to turn off , very small plastic box that the receiver sits in ran led grill lights on my 2019 Gt Mustang, remotes are really nice for the price , got way more than i expected, , thank you

Excellent item that gets the job done cheaply. Remote functions easy to program. Nice compact relay box.

Dislike: the plastic enclosure needed trimming so that the wires can pass through. Like: instructions are clear and easy to follow. I measured the current draw @12VDC in eash of the 3 modes. Standby: 6 mA, Toggle (on): 67 mA. Latching(on): 37 mA. I'm using 3 URGENEX 3.7v Lipo Battery 600mAh with JST Plug 1S Li-Po Battery with X5 Battery Charger for UDI U817 U817A U818A V959 V222 V929 RC Drone Quadcopter 5PCS Aircraft Batteries in series to power this receiver. The receiver needs 10-14 VDC. Using the Latching mode reduces the current draw by half. You then use the key fob (A) button for turn on and the (B) button to turn it off. Range is pretty good (433 or 315 mHz).

No complaints. Instructions are mostly clear. Appreciated the case.

Although Alexa and Google Home can replace a lot of projects that previously might have required a wireless relay, there are probably many where a pushbutton, wireless relay might still be useful. I wanted a portable backup alarm for my car but didn't want to mess with my car's electrical system. With this little wireless relay and a a couple of other components also purchased on Amazon, I made a simple portable backup monitor that I leave in the back seat. When I am backing up, I open the rear window a bit so that the alarm can be heard by pedestrians. I turn the alarm on and off with the pushbutton that is included with this inexpensive relay. The wiring is simple although I initially managed to screw it up. QIACHIP technical support replied promptly to the question I asked in a message on the Amazon website and solved my problem.

Everything is in top condition

This item has a clear note saying “ Maximum input power is 250 V” while it is not. Connected it to a 110v volts and the thing literally blew in my hand, now I have no item to return, and also lost my money. To make it even worse, the remotes do not work with other 433mhz receivers. Not recommend. Ps: fortunately I was not seriously hurt.
