I just purchased the Xiaomi Mi Notebook Air. I was looking for it for a long time actually. After a long research I finally found it in Trading Shenzhen website for a really low price compared to other online retailers. After signing in and ordering the product the real service started to come out: the tracking of my package has been the best I've ever had so far on any platform, the mails about customer service satisfaction have been always in time with clear informations and comforting word about the order and the warranty policy.
If you're looking for a reliable chinese online retailer and you're not sure about which one to buy from purchase from Trading Shenzhen, trust me, you won't regret!
