1: it is impossible to be less than a week old, just the shipping from China to here takes that long.

2: if you understand how business work you would understand that big companies are the once that all the batches of Bitmain and then re-sell it

3: I told you that we open them up and test it so we deal with the crap of sending them back, I dont want to deal with people give me someting after I ship it to them. If you notice from the whole batch I just take a picture to 2 of them because they other we keep them for us. But I am not here to explain you anything, either buy it or just move on. I have no time to lose.
