This is on Avalons site.. "For example, Avalon will not be responsible if a Bitcoin bug is introduced rendering it useless between the period of time which a batch of Avlaon units are build."
What does that mean?
It means: If Bitcoin stops working for some reason and your ordered and paid for ASIC miners are rendered useless before you get them, too bad for you, sucker. You already paid and you'll get them, even if there is no use for them. Say bye bye to your money. No refunds.
At least you'll have a coffee table with more class than Rassahs'...
