## Customer Reviews

### ⭐⭐⭐⭐⭐ See above.
*by K***. on July 31, 2025*

No wiring schematic included, but available on line

### ⭐⭐⭐⭐⭐ Very versatile.  Runs off 5 volts, and will trigger with either a LOW or a HIGH.
*by W***E on February 18, 2024*

So far I have used these is several projects controlling lamps, valves, attic light....even the shop radio. Super easy to use and so far have been very reliable. I really like that you can send a ground or 5vdc to energize these, so there's lots of projects that don't have microprocessors, just some photo transistors or other sensors. These are truly handy, get several.

### ⭐⭐⭐⭐⭐ Has built in diode
*by T***Y on September 3, 2024*

These are great because they have the built-in droid that protects against flyback voltage. I use these quite a bit. I have not had one break yet.
