XO Vision is a leading designer and manufacturer of Automobile Electronics and accessories. XO Vision products are carefully designed to ensure cosmetic appeal and are thoroughly and rigorously tested to guarantee superior quality. Products are first tested by our Quality Control Center in the United States of America where they undergo heat resistance testing in our heat chambers, durability testing, and various other tests to make sure that the product can, and will, withstand the most severe situations possible. Products that pass this testing are then produced at our factories at which point the factory manager personally oversees the testing process there. After products are assembled and ready to ship, they are then tested by our Inspectors in Hong Kong where they make sure that the products abide by the strictest industry standards.
