I recommend you buy it on idle fish. Although most of them are second-hand, they are really cheap, at least much cheaper than a treasure. And it's easy to find what you want (although it may be expensive). Because Tik Tok is chaotic, the quality of supply cannot be guaranteed. Once there is a problem, there is no one to find and no platform for you to solve. Moreover, due to the lack of effective supervision of platform sellers, many merchants do not implement the return policy in accordance with the relevant regulations of e-commerce, and their after-sales service attitude is bad. In Tik Tok, the host often exaggerates the product. Before, many consumers complained that the goods purchased on the Tik Tok platform were seriously inconsistent with the goods in the live video, and the false propaganda of merchants became a "routine operation", so don't buy things on Tik Tok. If you want to buy something, you can go to the official flagship store.
