Nice little boards to have around
Board looks well designed and clean build - no funky soldering and stuff. Worked as expected when connected to a nodemcu microcontroller board for a wifi switchboard I am building. The physical size of the board could’ve been a little smaller, but at this price I’m not complaining.

Good little relays.
I like the ability to choose high or low trigger. One out of eight didn't work; but, luckily I didn't need all eight and for a buck+ apiece, I'm happy!

Not always 3v compatible
Versions of this are sold to be activated on 3.3v and others are sold for 5V. Several in the package work on 5 but not 3.3 as expected. They were cheap enough that it’s not worth returning, but I needed a large pool of them to find a few that worked on 3.3v

Works well, garbage screw terminals.
These are the worst screw terminals. They are so bad I want to buy some better ones to solder on to the board. They don’t hold the wires securely at all even after CRANKING them down.

Exactly what I needed for my projects
Performed exactly as it should. Would buy again.A little confusing on the jumpers and the 3.3v input and the trigger contact. I found that VCC was power to relay, 3v command pin was the activation pin, and the ground of course worked as ground. After I figured that part out for my project these worked well for what I used them for (low voltage application). I think the seller explains this in the product documentation as well, I'm not sure I read it until after I tried to use them though.

They do work. Good price.
