Who even spends that much and buy ASICs from sites like Alibaba or Aliexpress?
I know some merchants have the Trade assurance program, but there have been several complaints about people buying equipment that stops working after a few weeks..... well, after the trade assurance period has expired.
It's funny but is entirely possible they place something inside to make that hardware to stop working after some time, like a timed small bomb, it could be a circuit or many circuits, a board to be fried, to me in the end they are all scammers in some way, asic market is scammer's paradise.
