Yousan sent its product to professional testing organization and got a REACH test report to help customers certify the products can pass REACH test.

  After sale service

  Yousan factory does not produce poor quality products with extremely low price. (Always remember "You Get What You Pay".) In Shenzhen, it is very common that some customers give very low traget price to several usb factories, some factories think even if they do not accept that order, some other factories will accept the order, and produce the orders with upgrade chipset to guarantee the margin. The result of this vicious circle is that more and more factories try to win orders with extemely low price(even below cost) first, when they get orders, they will think how to produce the orders to make sure there is margin. For these kind of factories, win order is the first thing.Yousan does not do such things, because when products are delivered to end users, too much peoblems will come up. On one hand, it means yousan will lose good customers. On the other hand, yousan need to pay a lot to solve the problems. Yousan will not risk of losing customers and paying more to win orders with unreasonalbe low price.

  All products from yousan, will have 1-5 years warranty. (udp chipset=1 year warranty,normal chipsets=5 years warranty)
