Hi, i'm going to buy an ASIC on alibaba

hi, i’m going to buy an asic unit on alibaba.com, for my client, has someone bought on this page from a china asic factory? without being scammed or getting fake products (I’ve seen very bad reviews on the website about the manufacturers of asic)

Does anyone have any contact from a Chinese factory or vendor to buy new products asic servers?

please and thank you very much from everyone!
