BAIKALS never ROI
Better keep your bitcoins ! You will have much better profit.
X10 is having stability isues and the boards are stoping to hash and red lights on ! This is the reason BAIKAL is delaying the X10.
You will see how many they will start to complain.
And if you have such a problem Baikal will tell you that you broke the miner and to send them the defect board back for repair (with courier of course )
And then you have to pay also the shipping to get the fixed board.
Even if the product will arrive damage BAIKAL will tell you that you broke it and you go the same route....
They are so good that they never send defect products

And if you ask your money back they just don't answer you ... its the simple way...
Buy BAIKAL buy !!!!
