Relay sticks when switched on.

Problem with all 3 relays in the box. To reset them you need to click above. I needed her for work. I carefully cut off the plastic top of the relay and they worked great. I think the blue case is too close to the switch. I got them to work and everything is fine. You need to know what you're doing to remove the top half of the blue case.

Pros

Easy setup

Cons

Upgradeable
