So, even if another company is trying to outbid us for your business, they simply can't do it. All you have to do is tell us about the lower price and we'll send you a check for the price difference plus another dollar. That's how our guarantee works. Oh, and we even ship your order to you for free. Our Equinox DVD players and car monitors are also pretty easy to install for many owners. So, come on. Give your kids what they want and ensure yourself a lot more peace on those long family road trips while you're at it.
