Before working with ONLY LED, I had tried at least six other factories in China, their prices were way cheaper than Onlyled, but warranties were useless — most never responded after shipping. ONLY LED’s pricing is higher, but they provide a true 5-year warranty and reliable service. When I had some module defects, they replaced them immediately. Their products cost more, but the honesty, reliability, and real support make it worth it. It is my choice to work with onlyled.
