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.

Buy something better
This relay has experienced failure again after just a couple of months of use. It's not the mag coil that fails but rather the contacts are of such low quality that they corrode beyond their ability to conduct power, and fast. I have had to change two of these so far and am on the third one. The seller will ship replacements but who wants to keep replacing them? I have to travel in my RV with a spare. This relay has never been exposed to the elements. It's safely mounted inside a sealed bay. Be aware of any brands that look like this, they are all the same.

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.
