I Just found out that Doran Manufacturing no longer sells the Doran PressurePro system. Is it true that theirs is the same as L&S's PressurePro? And that "PressurePro" is the actual name of the product? I've been told now that although Doran does manufacture other products, they did not manufacture PressurePro-that Doran and L & S Safety Solutions both bought from the same manufacturer. Has anyone bought L& S's system from L& S? How is their customer service?
