### ⭐⭐⭐⭐ 







  
  
    I ordered wrong Part HELP
  

*by G***R on Reviewed in the United States 🇺🇸 on May 27, 2021*

I ordered wrong part for a project coming up.  Then I realized it 12vdc and I meant to order 5vdc.  This is a good product and have used their products before.  Due to time limits this is the only way I can contact the seller!

### ⭐⭐⭐⭐⭐ 







  
  
    Very solid relay kit. Nothing cheap nothing flimsy.
  

*by A***R on Reviewed in the United States 🇺🇸 on December 29, 2018*

This is a "heavy duty" relay kit. Very solid.  3.2V friendly, this means you can trigger the ON/OFF using a 3.2V IoT device. The High-level trigger works as advertised.  I am designing a home thermostat, for the thermostat  24V AC this relay kit is a little too much, still I love it.

### ⭐⭐⭐⭐⭐ 







  
  
    Works well with Arduino UNO.
  

*by S***K on Reviewed in the United States 🇺🇸 on November 7, 2019*

Works great. I used this to switch 110 volt lights on and off with a Arduino UNO for a Halloween display, it probably cycled hundreds of times in the course of the evening without a problem.
