            I'm impressed with this product and Keyline as a company.

            This battery Isolator works great! Easy to install once you figure out where you will place it.

            Simple quick install, the kit comes with almost twice as much wire than I needed for my 2016 silverado 1500.

            This is a neat product, the design is simple and you can't really go wrong it works well so far.
