Seems to be good quality. I like that it came with wire pigtails. I’m using the relay to power my LED pot lights on my boat. Seems to be working perfectly. Let’s see how long they last.

I have 2 of these on my truck powering and controlling some aftermarket accessories and they do a great job! Easy to work with and understand with some entry-level electrical knowledge. The wire gauge is accurate and makes for an easy connection no matter how you decide to connect it. Haven't had an issue with water damage or corrosion so it's safe to say the seals are good! Gonna use these for any future projects I have that require this type of relay.

I’ve used these relays to wire several circuits on different cars. Good quality relays and great value.

We originally bought these to bypass a burnt terminal that was causing a fan issue in our Mustang. We found another issue and didn't use them for that but they are well made. We did use one to fix a trim relay on one of our boats. Worked well for the tabs.

I'm using this to run a Viair compressor on my truck via a Rough Country air bag controller. It turns the compressor on and off when the controller tells it to. Does a great job. I like the high gauge wire as it allows me to run the compressor, which can go up to 20 amps. Wiring is easy and straight forward. It just works.

These relays seem to be good quality. I have installed two of them so far and no problems with them. The first one paid for the box, so it's a definite win.
