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, I heard some asic companies were doing that to random ltc asic miners back in 2013, to me in the end they are all scammers in some way, asic market is scammer's paradise.
It's less of a headache if one just stick with graphic cards instead of Asic miners
1. ASICS can't be fixed if something go wrong, you will need to buy complete power supply if that's the problem and if it's not you will have to send out machine to get it fixed
2. Once they give problem your rig is going offline, but not GPUs you just need to remove the bad one and others will keep mining
