This system is overpriced and overrated. Forget them honoring the warranty also. Decra has the worst customer service and staff. Steer clear if you expect any follow up. They are an overpriced system especially for anyone that is not located near any of their warehouses (ex. California or Texas); for some reason even if you are closer to Texas, they will ship from California, not sure till this day how that makes any sense. The shipping costs are enormous and the demand is just not there. If you want any clarification around installation guidance or costs per square for materials, DO NOT ask Decra employees as they are useless. They will not provide accurate information. I'm not quite sure how they are still in business. They are a small company that do not stand by their customers but even worse, they hire incompetent employees. Not worth the hassle or the costs of installing this system.
