It's actually pretty interesting, you can estimate your position in the order queue based on their BTC address.
https://blockchain.info/address/1QB8Ds5KbGYBLQa5RyDQ2sVUeSKWf7qgkZ
You can see 55 transactions of 2.4BTC into it on the 11th from the last sale.
After the increase, there was a bunch of transactions for multiples of 2.65 (and what I believe to be a 4 part transaction for 31.8 or 12 units), totaling 31 (+12) for a total of 43 units at 2.65.
You then see the big increase after the price drop, at this time 81 multiples of 2.2 (plus one of 3.3 without a corresponding 1.1). There's two transactions of 22BTC that could be 500 U1 orders or 10 S1 orders, and of course small orders could make up a single 22BTC U1 order, though I think it's unlikely that someone who paid in multiple transactions would do it in exact multiples of 2.2 If I had to guess, I'd say at this point they've sold 61 S1s and 1000 U1s since the price drop.

Please watch out this website is very buggy - I made payment right away and Bitmain says only needs 1 confirmation
Had 10 by 30mins still website not show I paid now my order has been canceled and yet I paid with over now 15 confirmations!
Trying to get a reply from Bitmain or his email team is near impossible.
Sadly I now fear the worst :/ Anyone else had this problem ?

Negative - took 15-20 mins to get 1 conf if I recall.. once I had 1 confirmation, site reflected good to go / valid.

don't fear the worst - the bitmain team is one of the best and most legit. Remember, its the middle of the night in china so they likely are not watching emails closely

Good news
To hose who say 2.2BTC is too high, you need to review your calculations - difficulty is beginning to settle a little towards 20% increase per jump which results much differently than those 96%/month estimations. I think that at 2.2BTC, you should expect it to mine 2.1-2.6BTC in its useful lifetimeI have units from the original 4.75 and 4.25 auctions/group buys, and looking at the income they have provided, they have made *approximately* 4.3 and 3.95 BTC each - a little lower than bitmain's estimate, perhaps because shipping time/delays and system setup/down time were not factored in. - In either case, both systems need to pay off far less than 2.2BTC of their costs
The product is simple and fairly energy-efficient. it would be nice to see an option added to purchase units with a secondary fan installed, or perhaps slightly quieter fans, Considering I have added a second $20 PWM fan on each unit ive bought so far
http://bitcoinwisdom.com/bitcoin/difficulty
My estimate is around 35%
Second please let some who participated in those group buys to comment reality against projection
By reality I mean separate pool/s account and the ACTUAL TRACEABLE income
Have in mind that in reality mining income is at least 5% less iff all is super fine during the period and you do not need calc for that
maybe you missed what i said - the 4.75BTC unit IS very close to paying for itself. I run at 190GH and $0.10/kWh. Its not as close as bitmian is suggesting, but i had delays in shipping, setup, and some internet outtages. In either case, I expect the miner to pay for itself sometime around, or just after, the next difficulty jump in 9 days
its a little tricky to estimate the exact income, since i now have 3 antminers and a bitfury mining together. All mining is a single wallet address, and I have used a few pools (eligius, btcguild, and ghash.io) at different times and sometimes sent payments from them to btc-e or to bitmain for purchases rather than into the mining address - so I have to round some numbers and make a few estimates on these details.
PS: I am using Cougar 120mm PWM fans (<21db, 70cfm) as my secondary fans, and i beleive they help pull a lot of the excess heat away

Just wanna state that the antminer S1 from the first firesale of 30 units @ 2.4btc showed up =) and as he stated, because I pointed out a bug on the site, there was a free U1 USB miner sitting in it ...woot
Smoothest ASIC purchase ever.
Please setup a separate pool account so you can be able totrace exactly your income and be so kind to post if you ever Meade btc roiSmoothest ASIC purchase ever.
Thank you very much
If you wish of course

Whatever happen to the days of people making the decision if the price is to high by not purchasing?
Man everyone wants to bitch about price.. if you don't like it.. don't buy it.

Mining Stably, Delivering on Time, if not Pre-Shipped.
Now we need only 1 confirmation after you paid the bitcoin. As we will double check before we finally ship, We believe double spending attack is not rationale.
2.2BTC/Unit, Shipping included.
The first batch of Antminer buyer is going to ROI in a day when I write this post
When Bitmain first introduce the miners on the market, we sell on 2013/11/23 a 180GH/s ANTMINER at 4.75 BTC. some people fear the increasing of difficulty, while some other community members bought it.
What if these miners started to mine on 2013/11/25, how many coins has the S1 mined, assuming not overclocked, 0.10$/KWH, 836USD/BTC? The number is 4.697BTC, electricity bill deducted. The miner who bought S1 on 2013/11/23 @4.75BTC per unit needs only another day to enjoy the ROI when we write this post, without overclocking.
Now according to our model, which has been proved accurate or conservative in the past, we believe the 2.2BTC is profitable price for the miners, and a fair price to distribute the future mining revenue between the Bitmain and the mining community.

I have paid 2.65 for one that has not even shipped yet!!!! 
"We created a myth in bitcoin community: no pre-orders, shipping on time, even pre- shipping. We are earning more and more trust from worldwide customers." how long will that last if you make a firesale and then sell the items cheaper a few days later??
So please Bitmain, answer your emails and give us all our "unshipped" Ants for 2.2 BTC

And in 25 you will get tracking if all is good q1 march delivery
And while you are counting days until March there will be two jumps with 40% this is my feeling
And so on and on just two magic words ASIC on stock reliable delivery and the fact that there are no deals around does not mean that we have to buy that is all
I'm not sure why you're saying that if everything goes well that a unit that ships on Jan 25th will arrive in March. While it's a possibility if there are huge customs delays, the last one I ordered was on Saturday night, it shipped on Monday and it's scheduled for delivery today. And while you are counting days until March there will be two jumps with 40% this is my feeling

The problem With 25 jan shipment is that China is closing for ny and there is just on business day which means that it shall be out of people's republic before that the route is going Taiwan probably and when it reaches there they will be closed

Is that a jocke ?
2 btc?
Check your math dude. In Feb diff which is unknown since something big is happening behind the scene not more that 1 BTC and i doubt even at that price it will ever make roi
Any way Bitmain is a smart businessmen with a good record which deserves our respect . I wish all of us the customers to be at least half the smart compared to him
Besides CNY is knocking at the door and that is only time for most of the pople to meet their families. I would not blame China DHL or EMS employees if they mess up something with some orders and this get delivered in march. For sure Bitmain will do his part and provide all of his customers with tracking as promised
PS: the picture in most optimistic scenario

I updated them (changed the difficulty to the 2.07B estimate for the next jump, changed power to 360W, and removed the BTC/USD increase, changed the lower diff increase/jump to 5%)
bitcoin mining profit calculator
Even with those changes that calculator is showing break even in June, with difficult 11x higher than the next jump at 22B
You forgot that there is at least 1 diff jump before those get to mining. I would love to buy more of those, but those are just too pricey for the risk. 1.5 BTC I could manage.
