I ordered a Baikal x10 about 3 weeks ago. The contacted me saying it's not in stock even if on the website it said it was in stock. The miner arrive in stock a few days later, i got notified via email about this, paid for my order and it was shipped. I received the package one week later. I've been mining with it for about a week and it's really silent and cool (compared to the antminer s9). I'm giving this 4 stars because of the stocks misrepresentation problem.
