Excellent

I bought one of these for use with an Arduino Uno, to switch various model railroad-related loads. So far so good!

Good, JVCC required option

I use this relay board because, the power required to activate relays is supplied by external power supply. I want to minimise the current load on the raspberry. I needed DPDT relays so i used two in parallele Very fast delivry

Impressed

Excellant quality product with creepage slots and opto-isolated inputs. Far better tahn the cheepies direct ordered. RobotShop is #1. AND when they say you will have it in 3 days--that's when you get it! Thanx RobotShop!

Excellent product

Being in engineering I was impressed that it has the high-voltage isolation grooves cut into the pcb and not just the isolation in the front-end. This is the proper way to do it on the power side of relays to prevent AC creep. (I have not tested their isolation characteristics though)

Excellent product

This is exactly what I wanted. Simple low voltage control for 4 standard 110V outlets (of course light duty use only). Direct control by parallel port data pins on old PC.
