This relay did its job well and still works after about a year. I used it for fog lights on a truck, maybe it was overkill to use but better safe than sorry. It’s waterproof and well sealed

Very durable relay and waterproof connector. I’ve been buying regular relays and they only last so long in the weather. This is an amazing solution to this. Terminals all stay dry, no shorting out in the snow. Great product.

I had to build a new headlight wiring harness for my 07 GMC TopKick and used two of these relays for both the high and low beams. They're solidly built, appear water-tight, and work fantastically.

Relay works amazing! Have it installed on a light bar on our side by side and it goes under water on the regular mud riding and it has yet to fail. Third one we have bought and will buy more as we load more accessories!

It has a nice connector with sufficient gauge wire in the pigtail leads, good firm connection/terminals, and a weather seal that seems to seal really well.Time will tell on the durability of the actual relay but realistically, for the price I'd say the connector itself is worth the money.

Using this to provide power to accessory horns mounted on truck.Things I like:- Very waterproof - perfect for under the hood- Case quality is very good- Metal mounting plateThings I don't like- Locking clip is very tight and tools are necessary to press down on clip to open case.

There were 2 problems with this product. (1) they switched the white and black colored wires. Instructions say 86 black wire is trigger, but 86 is the white wire. (2) The product was dead out of the box. I tested all leads and verified I had power to the relay, but the switch would never trigger so it never powered the device. Lost several hours messing with it. Returned for a refund.

No complains really. The build seems quality. Ended up using a Hella relay just for peace of mind. But the relay holder seems to be working fine for about a month now.
