## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    cheap, but work - individually wrapped
  

*by L***E on Reviewed in the United States on 23 July 2023*

So far they are working while being driven from a single pin from my ESP8266 development board. The connectors for the load wiring are a bit small for what they are supposedly rated for. More like standard hookup wire size. I have found one so far that had it's board corner broken, no good for mounting, but still works. Worth trying at the price, I have yet to see how many cycles they will run on my project.

### ⭐⭐⭐⭐⭐ 







  
  
    3.3V is a very nice feature
  

*by J***N on Reviewed in the United States on 1 August 2023*

All 8 modules checked out without any issues. It is nice having the straight 3.3V interface without having to adapt it to other circuits. This pairs very well with STM32 and RPi Pico boards right out of the box.Overall component temperature and relay holding torque seem to remain very good even after months of repeated use.

### ⭐⭐⭐⭐⭐ 







  
  
    desc & jumper purpose is not well worded, but they work as advertized.
  

*by S***V on Reviewed in the United States on 18 April 2022*

these work as expected. the jumpers don't seem to do what the desc says, but if you just leave them on as they come out of the package the part works as you'd expect & isolates between the HV and LV sides
