Nice review, will look forward how efficient it can be when underclocked, but out of the box it is weeker than S7's. How long have you waited for your miner to be delivered ?
Batch ones have started to ship i don't know numbers or any special information. If your wondering how long it takes I would contact BlockC for majority of people, if in China it's Ehash to ask as far as shipping date with new order. Those are the two official channels.
As far as 3rd party or re-sellers I can't give you a good estimate as so many. But again batch 1 is shipping which is good for those people looking to order.
