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

I bought this relay to put on my Chevy Truck for some new 10" Electric Radiator fans. I live in the Desert and it gets pretty hot around here. When I run the AC at an Idle the AC was struggling. So I added these fans and I needed a good relay to handle the amps and not get wet. This relay does the trick. So far I have had no problems and the AC works like a charm. One thing I did notice is that the picture shows a metal bracket and the one I got was just plastic. I would have preferred one with a metal bracket but oh well. Other than that it does what it should. I hope it last as only time will tell. UPDATE 9-9-13: Well it has been a year and this little relay is still going strong. Arizona heat has nothing on this relay..... UPDATE: 1-1-2015 So here we are over two years and this thing still rocks.

Great 5 pack of relays and matching tails. I had old relays taped together running my Fisher plow lights. Weird light issues had me questioning these relays. These straightened out my concerns about cross wiring, and made the connections truly waterproof. Bam! Lights work correctly again.

Used it to replace the ones on my Ford f250, worse great so far, tested them, all. All tested good. Been using for over three weeks the ones I did install. I took off the metal piece piece that sticks up, isn't difficult to take off. I like the metal piece in case I need to install an extra part, and just bolt it to side of engine wall compartment. I give it a thumbs up.
