thanks eveyone for the input.
I heard that the guy in the op has been removed from aliexpress for improper trading
What I will say is that I've bought over 50 items (boards, circuits, sensors, etc.) from aliexpress in the last year and the items have always arrived here (eventually...shipping is slow as hell) and the items all worked.
Having said that, I've bought over 50 items...and never spent more than $15 on a single item. Do I trust them for cheap sensors, breakouts and boards? Yes. Would I buy a Miner from them? Not a chance in hell.
I think this is how I would roll now with aliexpress, it's a bit safe, but I'm mean anyway.
Let's just hope sushi comes back from China with something hot.
