Best and Affordable
More Affordable than my previous one and still working perfectly.

Nice Product but Chinese labels
The product works as expected. But the NC, COMM, NO ports are written in Chinese. So, had to try it to find out which was what. I have attached an image to clarify this for future buyers.

worked like magic for me
worked like magic for me. The light indicators are specially good and risk free as it help try the functionality of the relay even before connecting a high voltage device.For some reason this did not work with 5V and had to switch to 3.3 volt in my raspberry pi. tried for 2 different pi's and the same outcome. All articles online seem to indicate that it should be connected to 5v. Irrespective works like charm with 3.3 and was able to operate an AC240 volt bulb and DC motor

Good Product
Really good product. Works with low current from arduino board. Can take about 5A current safely.

Recieved defective product
The one I got was defected. It did not trigger on input changes. I got Defected product for such high price.

reversed but works
if you are buying this please note in this specific module the nc and no are switched. so if you are entire logic is reversed. But it works.

Not buy this product if you are working with Node MCU and esp 32 development boards.
Product is absolutely fine but it's not compatible with esp 32 and node mcu .they require low voltage triggering so for that solid state relay are required.

Beware! No optocoupler, and tricky with 3.3V
Bought these to build some smart switches. As soon as I looked at them I realized there was no optocoupler, making it risky to operate with high voltage loads (see first picture.) As another reviewer mentioned, the relay terminals are labeled in Chinese. However, it's easy to figure out which is which using a multimeter/continuity tester. I've labeled them on picture 2 if it helps.One thing to be careful about is the behaviour with 3.3V signalling. Vcc must be 3.3V and not 5V if you are using a 3.3V signal pin. I got tripped up by this initially when I connected Vcc to 5V and tried to drive the relay with a 3.3V signal pin. This did not work and the relay behaved like the trigger was always low. I then tried using 3.3V for Vcc and the relay started working as expected.
