These worked well. I like the price and hope they willl last.
I used these for the circuitry on 1970's Jeep Wagoneer rear power window and they worked flawlessly. I would EASILY buy these again. The recepticles are well made and include small metal mounting tabs which I did not use. The relays work. The wiring is true to the stated gauge sizing. I paid about $8 for the pair of these in April 2025. At $4 each, these are a good value assuming they last. These will be getting near daily use so I will report back, especially if these prove to be unreliable.

Worked awesome for my air compressor setup
Used this relay to wire up the air compressor for my air bag suspension on my pickup, and it worked flawlessly. The color-labeled wires made installation super straightforward, and the 12AWG wiring feels solid and well-made. Handles the load without any issues, and it gave me peace of mind knowing the compressor is properly wired and protected. Great value for the quality—definitely recommend it for any automotive accessory setup.

Good relay
The relay is somewhat bulky, but it's a perfect option for an underhood environment or perhaps even a marine environment. I'm using it in the engine compartment of my car. I'm happy with it. Works as expected.
