Ordered a crypto miner from a merchant on Alibaba. After 3 weeks of no communication they finally shipped it. What arrived was a poorly packaged and non operational Miner. They just threw it in a box with some loose plastic stuffed inside. I applied for a refund through the Alibaba trade assurance program. They rejected the claim and left me stuck with a $7,800 worthless piece of junk. Don't make the mistake of thinking that they operate like Amazon or Ebay. Nothing more than the opposit is true. Their trade assurance is a scam. I will never do business with them again.
