Review: I love the relays, the clear view is awesome and nice to see, great quality materials and very complete set, the only "flaw" is that the relays don't sit completely into their spots. You can see on the pic how they're crooked. Did I said that I loved the relays?
Review: I use these on my LS swaps and wire them into the Holley efi. They are great little fuse boxes. I replace the cheapy fuses, but the relays seem stout. I used to buy the ones you assemble yourself, but now just buy these already assembled. If you are doing some wiring....buy it. Don't run a row of relays down your firewall.

*by T***R on 6 January 2023*

Everything looks solid , only problem is, they claim it's water proof and it is in no way water proof. No seals and a hole where wires come out. Nice try tho. It will work as I'm installing it in UTV glove box, but if u want water proof get something else.
