Nice quality
The good thing about it it have a built-in fuse which make life easier, and a relief of the wiring hassle. So far no issues with the relay.

Fix the images
Carefull some misslabeling in one image that confuses common trigger wire and positive source. Ur relay will still work but you will be pulling power from wrong side. Best read the numbers on the relays and trace the wires

Great Quality, excellent design with fuse built in.
Super handy for adding circuits to cars and trucks. I would definitely buy again because I keep these on hand for regular use. It's especially helpful that the fuse is built into the body of these relays, easy to find and replace if there's a problem of some sort.

They work well.
I used these to install some ground effects (lights) and they work great and are easy to use. I like the fuse being built right on the relay. Very practical.

Great for customer lighting
This is a great all in one piece. I use these for a hi/low mod on OBS Silverados. They also work for foglights aswell. Haven't had any complaints on melting or popping fuses or relays. There is plenty of wire to extend and last a long time. Great value for the money.
