The seller is five stars and success in business. Led panels came in time set by the seller. Checked, connecting to the battery, burning very brightly. Leds are sealed smoothly without distortion. Came packed in anti-static bags and in a puffy. There are no complaints for shipment. I will make orders from this seller more. Seller recommend.
