Heavy duty and has lasted three years so far
I have had this relay installed in the engine bay of my Lexus RX 300, functioning to link the front battery to the additional battery in the trunk whenever the ignition is on. The relay has worked reliably for about three years now with no complaints besides one minor comment, be careful when threading down the nut on the Low voltage side. It is prone to stripping

Heavy Duty!!
Performed extremely well. No buzzzing or poor connection. Extremely well built and has been working issue free for over 6 months! Instalation can be a bit difficult due to size and weight. Not really a problem.

Seems to be ok for the money
We use it to power a 2000w inverter for the refrigerator and microwave on our boat where sometimes it will stay on continuously throughout the day and it hasn't let us down. As others have said, the terminals are awful close together but for the money, it's worth it.

Been doing great since 2020
Used this to replace the charging solenoid on my diesel motorhome. Originally used a White-Rodgers OEM relay and it only lasted about 18 months. This has been going strong since 2020 and I use my motorhome about 10 months out of the year with lots of miles.
