Anyone have one of these yet? I may buy 1 as a talking piece. Are there any group buys or distibutors in Asia? Im on assignment here in the Philippines 
Ours arrive tomorrow according to UPS

In another thread (I forget which) a link to a 30x14 cm (half a square foot) heat sink from Shenzhen was posted http://www.ebay.co.uk/itm/300-140-20mm-Aluminum-HeatSink-for-LED-Power-IC-Transistor-Module-PBC-/321199970078?pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item4ac902971e
By buying parts for a miner separately and putting them together oneself, one can avoid paying VAT. All that is missing is an economical board from Bitmain. If Bitmain wants to democratise mining they have to make a product that stands some chance of recouping its cost. It is most unlikely that the U3 is that.

If Bitmain really wants to support the home miner, the design has to be drastically simplified so that people can make a working miner with parts from their junk box.
Post what the MSRP needs to be for each unit.
Post what TH/s the units needs to be.
Post what the power consumption per unit needs to be.
What you are proposing is really an impossible unit at this point in time given the BTC drop. There is nothing right now that can be built to make a return and if it is only useful as a miner. Dead is home mining and possibly massive farm are dead as well especially those that do not have the cheapest hydro possible.
The threshold for UK 20% VAT is £15 (For duty it is £135) ie USD 23.96 http://customs.hmrc.gov.uk/channelsPortalWebApp/channelsPortalWebApp.portal?_nfpb=true&_pageLabel=pageTravel_ShowContent&id=HMCE_CL_000014&propertyType=document#P20_1804

https://bitmaintech.com/files/download/BM1382_Datasheet_v3.0.pdf gives 14.18 GH/s at 0.528 W/GH (Core voltage 0.72V, current 10.4A, Power 7.49W).
So the question is how many of these could be put on a board with a microprocessor, hopefully a switch mode power supply and a USB interface for $23.96.
Note that I've used the value 0.72 V whereas elsewhere in the spec the minimum recommended core voltage is 0.75
The situation in Europe seems to vary country by country. In France there is no threshold it seems, whereas some countries have a threshold of €22. Germany has a threshold for VAT of €22 but if the total VAT is less than €5, it is waived so the value could be up to €42 USD 52.41 (slightly more actually as Germany's VAT is 19%)
(The information for Europe I obtained from http://www.dutycalculator.com/ - but after 3 searches they ask for money and though I flushed my cookies it did not seem to help).
How can you profit from these while other miners are running on Ths?
There are still other coins next to BTC where you will be able to get some coins even with that hashrate. Even if it's only to generate "play money" to trade with.

It is not my intent to make a profit from this device.. it's $60... 60 bucks.. I just want a new toy.
Is there any reseller for EU selling the U3?

Anyone else planning on grabbing 1 of these or a couple?
There are a few group buys, as well as resellers: https://bitcointalk.org/index.php?board=137.0
Just opened a group buy for my area actually and I am talking to some co-workers. Althought it seems just using a re-seller is going to be the best way.

Another thing that's wrong with these devices is that they should be able to be run from a laptop power supply brick - so 12-20V input or 12 x root(2) V (12v lighting transformer)
I'm not sure what you mean, but they do run from a power supply brick?
My criticism of this device from Bitmain is that the cost is such that it can never be recouped. This is a coffee table device, a conversation piece, a piece of art, but it will never make the purchaser money.
If Bitmain really wants to support the home miner, the design has to be drastically simplified so that people can make a working miner with parts from their junk box.
To wit, no power supply should be included plus the purchaser provides a heat sink and cooling. It should be a barebones device which can run from a range of voltages (12V from an old ATX power supply or 18.5V from a laptop brick - in other words whatever is to hand), it should be available with an order quantity of one and the price should be such that no VAT or duty is payable. Delivery should be low cost.
I don't know what the market for such a device would be, but considering that the Raspberry Pi has sold 3 million, there is evidently considerable demand for products for hackers.
IMO that should be the U3 - DIY (Really though..??!)
There is nothing they can fix about delivery, there must be a distributor(someone buying in mass volume and selling out of NA). Mass volume is required for this though.
I am quite excited for the U3, I think I will get two and retire my S1's. 100 Watts for 120 Ghash, pretty nice. 100 Watts is cheap.
Is anyone from Canada/USA buying these and pushing them? If so pst me I'd like to buy one.
Everyone and their profits.. it draws 50 watts, so pretty much zero increase to the power bill. I can now support an alt coin I like for the cost of the miner.

at this point, USB miners are worthless other than conversation pieces
Imagine a phone or device with an ASIC chip that mines continually and are embedded in billions of consumer devices.
USB miners are worthless. The way we break the farms and get 'decentralization', as indicated in the thread title, is not with USB's but with embedded ASIC miner chips in devices already cheap and in mass production. Think coffeemaker / miner that is wifi / LAN enabled. Waste miner heat could help keep coffee warm.
^not going to happen. The heating unit in a coffee pot is a $2 metal coil with an on/offr switch. to put an ASIC in there would cost $50 of ASICs, controller, and wifi gear.
operating for maybe an hour a day - you will make an absolute pittance mining, FAR FAR less than the costs of the specialty coffee pot (which would stop working if the internet connection is lost!)

sounds like an S3+...
at this point, USB miners are worthless other than conversation pieces, and for a reasonable $200 you can get a machine that is still quite small, very quiet, and has a fighting chance to produce a positive return.

This is designed as a coffee table conversation piece - it's certainly not for hackers.

There is customs duty to add as well surely. VAT is to do with Bitmain. Below a certain price, no VAT or Duty is payable.
I buy lots of stuff from China and never pay any duty or VAT because I keep the cost and weight below certain amounts and perhaps because the vendors lie about the price I paid. Of course this is not possible with a minimum order quantity of 20. Perhaps Bitmain should team up with some of the vendors in Shenzhen that one can find on aliexpress.com

... You can't complain that Bitmain isn't illegally underdeclaring the value of goods, that's not a valid expectation. Pay your taxes.
I'm complaining that a DIY device is not being marketed and that the order quantity is ridiculous. There would be no power supply included and it would be up to the recipient to bolt on a heatsink and cooling. I've got plenty of heatsinks and cooling fans from defunct processors. With the cost of VAT and duty and the mark up of middle men, these are being marketed to the naive. How is that for ethical company behaviour ?
Additionally I pay all the taxes that I'm asked to pay so I resent your allegation that I'm not.
1) This is NOT a DIY device
2) Don't buy it if you don't want to
3) I resent that you're resenting that I resented that you were asking Bitmain to underdeclare the value of imported goods in order to avoid you having to pay taxes.
I'm perfectly aware that it is not a DIY device.
You're helping to market a device that will never make a cent for the purchasers.
I was asking no such thing. I just remarked upon how it is that I've never paid VAT or duty on items from China.
It's true, there was no request to lower stated cost for customs or taxation purposes from what I read.
Dogie, if your role in this thread is that of a company representative you should temper your words and act accordingly.
And to Tupsu's point, it doesn't matter where the added expense comes from; it the product costs too much (net to the consumer) then it's "No Sale". Don't create friction in the purchase process. This isn't Q4 2013, when even rational people tripped over themselves to throw money out the window.
Dogie's role in the company BitMainTech is limited to Technical Support Employee as far as I know.
So, this post should be taken as Dogie not as a BitMainTech employee.
Ignore Dogie if you can't digest his double playing role.
