Just as a reminder to anyone who has tried to cancel their order, just because KnC are scrabbling around trying to release firmware updates and paint a picture of success on their news releases, it doesn't change the fact that they have previously admitted this device is limited to where it can function (cannot actually be used for all scrypt applications), which runs contrary to the sales description so once you have notified them that you are cancelling on the basis that they have not met their performance obligations, there is no more wiggle-room for them to keep stringing you along on the basis that they'll eventually fix these performance problems.

They missed the boat, the units weren't as specified. Dangling a 'soon' scrypt-n carrot in front of people's noses now smacks of desperation.

If they had any sense they'd accept a slight-smaller profit and mine in their arctic data centre with these units and do the decent thing of refunding people who have instructed them to cancel the order.
