Great customer service (Chris) - need to have experienced installers who can recognize an incorrect battery which I fortunately caught. Also, had additional drop-down menu selections for special vehicle models. I have a FORD - F-150 "King Ranch" mod but King Ranch wasn't an option to select and it has an entirely different battery requirement than a regular Ford - F-150. Could've caused the customer a total inconvenience or vehicle to not perform (electronic fuel injection) properly not to mention the wasted man-hours. Installer did not knkw or believe the different battery (obvious size difference) would be a problem. Not a good biz model guys.
