Package was ripped and then re taped. No big deal. However when I opened it, it seems as if I got a return. Looks like it was already mounted and used. Last but not least there are no markings for positive and ground. Over all not happy nor satisfied

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.

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.

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.

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.

Screw for 12 V triggering came loose from inside. Fortunately internal contact is still working. Otherwise the coil was good for scrap. So be gentle while screwing, product is fragile.

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
