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

Installed in my RV.
This product works well. It is somewhat difficult to mount. The contact points are a little too close together. These deficiencies are understandable given its low cost and small size.

Effective
The power cut off was effective and worked as described. The item shipped fast and was packed well. My only issue is that the installation instructions were not very good, however with a few minutes of online research you can get what you need.

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.

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.
