  • Saved me a bundle
So my son's car was having a dead battery every next morning and we could not figure out why. I replaced the battery since it was under warranty and the battery would still die. I went to a car electrician and they wanted an arm and a leg, and to keep the car for few days so they could see the failure and try to figure out where the battery drain was coming from. That was not an option. Read online that there is such a switch and figured let us try that and see what happens. The instructions were easy to follow but the text was really small for me. In my case it took about 30 minutes because the area to work on was really tight. But is was fairly easy to follow. And voila the battery stopped dying and it worked perfectly. This was done in colder weather, and since then we have not had a dead battery in the morning. Highly recommend if one is having parasitic draw on their battery. The tools came with it too which makes it easy for some who do not have the tools to install it. Highly recommend. ... show more

  • Very Good, Vendor Resolved Issue with mobile app
Style: 500A mobile control
The app I downloaded was not in English. I contacted the vendor and they asked me to wait while they upgraded the app. Plus they issued a partial credit. Other than that, the hardware seems excellent and does work. Although I have to wait til I have used it for a few months to know further. The mobile app could be better but I shopped and shopped and there really isn't anything else to compare. So I do appreciate this product very much. Plus the vendor was fast to respond and very earnest to resolve the issues. Thanks! ... show more

  • Works as described and easy to install.
Style: 500A mobile control
This is the second device that I have purchased. After I put the first one on my truck I had to get another one for my car. Works exactly as described and super easy to install. Now when I don’t drive my car or truck for weeks, both crank right up without me having to go under the hood and do a manual boost. ... show more

  • Caution-electronics interference-2020 Dodge Charger
Style: 500A
Will interfere with many electronic functions such as AC, back-up camera, performance screen, etc. The constant current must not be enough to maintain the memory in a newer vehicle.

One of our vehicles has a draw and can't find it. We tried other types but this one is perfect. Don't even have to pop the hood to turn it on and off
