I manage to get a Baikal Cube miner.
In real world it does 310Mhs at 72Watt, fan speed at 55% keeps the miner at 47C.
It is a very nice piece of hardware if you can get hold on one.

Baikal official website is crap and you will never be able to buy one. Maybe it is just for marketing purpose.
I guess the manufacturer keeps them for themselves to mine.....
