Review on DB Electrical BSL0006 Battery Isolator by Donald Vargas

I spent several hours connecting these batteries to the isolator I bought and it never worked. To make matters worse, I called the company to ask about tech support, but there was no tech support. And they couldn't help me. It was just an answering machine. DB Elektro will not help you with your insulators. How can you sell a product without having instructions or technical support with it? $130 out the window. I highly recommend buying an isolator from another company, this three battery isolator turned out to be a complete mess.
