Ground triggered relay
These operate when you ground the input. Keep that in mind with your intended circuit. Out the box worked with zero issues. I upgraded 4 single relays to this and the design is much more compact. Good value for the money.

Well made and tested top notch
I bought these to go with the Arduino board and have not used them yet. I did run tests on them to be sure they would work properly. They work great when tested and will function perfectly when programed. The board looks great, the soldering is clean and the parts are all well mounted. I have no doubt that it will work as advertised when it's time to go on the job.

Easy to use but don’t last long.
I built a project with these. The relays worked well at first but shortly after one of these relays stopped working. I will not rely on these in the future.
