Review: Got a set of these for my arduino projects and thus far have had no issues with them. Easy to use, easy to hook up, seem to be made well enough. Pretty happy with them.
Review: I used these in combination with a motion sensor in order to trigger my Halloween animatronics. They worked great. Planning on ordering some more later for other props. They were easy to use and so far no problems with them.

### ⭐⭐⭐⭐⭐ Review
*by T***O on 17 December 2024*

I'm using these with ESP32 boards and all is good. I power them off the 5 volt USB feeding through the ESP32 board and the controlling signal is directly from one of the GPIO lines configured as an output. So far in my testing I haven't had any problems with spikes on the power supply lines causing problems for the processor. The one minor thing to be aware of when using a 3.3 volt controller (i.e., an ESP32) is that the relay likely needs to be set up where it's triggered active-high vs. active-low. If you try to use them active-low, the "high" state of the GPIO output may not be high enough to keep from triggering the relay. At least... that's been my experience.
