Has anyone ever bought a mobile phone in Tmall? What is the reputation and quality of being able to shine?

This store is Tmall's blackest by far. One word is profiteer. The electronic products he sells are all highly imitations, and the naked eye can't see any defects in him. In order not to let the people find the loopholes in his mobile phone, this store has found a large number of people to brush the reputation of his store and let Tmall think that his things are genuine, so as to fool Tmall. In fact, as he described it. The service of customer service staff here is extremely poor. Before you confirm the receipt, he will pretend to please you and let you relax your guard. After you confirm the receipt, he will hack you and make you suffer losses. His series of hardware and so on are all high imitations. In short, whoever buys it is unlucky!
