Hello, dear, I suggest you go to the officially authorized website to buy products, and I can assure you that they are genuine. The prices of promotional activities of various dealers will be slightly different, and there are real and fake online. It depends on whether the landlord will see them. There are so many fakes such as electronic products and cosmetics that it is difficult for some non-professionals to distinguish them. However, there is one thing, like these things, similar goods, cheap and not good, especially mobile phones. Hehe, I have five years of online shopping experience.
