If they said that it will ship between Sept15-30th and they consider up to 10 days not late then I guess they are up to their word. Probably no BTC refunds

?! They are technically over 10 days late now, though...

My units technically shipped "on time", however if they are under hashing I will not consider them "on time", I will only consider 4.86 units to be "on time", if the units hash at full speed, then I will have little recourse for having been an early adopter and already out $1000 based on sale price not to mention the missed weeks of mining. Caveat emptor.

However if they do not hash at full speed then I will not have received the merchandise which I ordered and paid for and I will want to return them for a full refund, or at the very least have the price difference refunded in BTC, PLUS coupons... Coupons alone are not a compensation when in order to receive the value one has to spend even more money with the company.

I would also wager that they printed hundreds or thousands of shipping labels yesterday, which will be labeled the "10th", and they will claim shipped on time even though they won't be picked up until Monday the 12th... :/

Don't forget about their disclaimer on product page Hash Rate: 4.86 TH/s ±5%, although it has always been -5%. But I do hope everybody gets good per spec working units including myself.

Well, they keep changing that "disclaimer". At first it was ±5%, then they changed it to "Optimal hashrate 4.86TH".
Anyway, both batch 1 and 2 has the same disclaimer. If you get the units that can't reach 4.86, you got the faulty batch 2, its that simple.
If they give me batch 2, when I paid for batch 1, I will consider it a scam.

4.8-5%= 4.6
4.6+5%=4.8
So I take it there is overlap between the two

To me it is 4.6 batch 3 and batch 1
4.4 batch 2

Ofc there is a overlap. But the fact is this:
When you produce chips, everything is made in one "batch" or plate or whatever you want to call it. When the batch is done, they cut it into individual chips.
Then they test the chips to check the performance and stability. I guess this is called Quality Control.

Intel example:
When the batch is done, the good performing chips (that has proven stable at a given performance) are labeled as "Intel" processors.
The chips (from the same batch/plate) that are not stable at the target clock/performance, are underclocked to a freq that makes it stable. And labeled and sold as "Celeron" processors.

Do you see where I'm getting at?

What Bitmain has done is this:
They tested the chips from batch 1, and figured out that some of these chips do not perform as the BM1385 are supposed to.
What did they do? They took the poor performing chips, placed them on hashingboards, and shipped them out to customers as S7 miners anyway..
Why did they do this? If they didn't, many batch 1 S7 orders would have been shipped late, and they would have been forced to pay big compensations.

This is what I believe has happend, and is the reason why I will call it a scam if I get some of these celeron miners..

Someone please correct me if I'm wrong, I'm assuming ASIC chips are made the same way as CPU's.
