Good Quality, Works Well!
Easy interface, saves time building. Used for added accessory control in my truck.

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.

Exactly what I needed
I always find the Elegoo products to work as "advertised" . I can't recall ever having a quality problem. They are perfect for the small DIY smart home projects I buy them for. In this case the the relays are exactly what i need and perform as expected.

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.

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.

Work as described
Used this as an interface between an infrared break beam sensor and a laptop for a slot car lap timing and race control station. Only issue I had was that the current interface software was not compatible with Windows versions before Windows 10, but was able to find the legacy interface software.
