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.

Works great

I added extra batteries to run a truck camper without killing my main battery and this works great. Simple to install and i have no had any problems in the pay few months and i use it every single day

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.
