it's joke!
This is a cool idea and 12 months ago would have been totally worth it, but with the difficulty rate rising exponentially they really don't make economic sense do they?
Wowo what a rip off!
Not a great deal, but far from a ripoff.
If you are not paying for the electricity then it is a no brainer to use GPUs but for us in the real world we have to worry about paying for what we use...This may not make the best sense right now at that price but the only way a project like this can improve is if there is demand. What would a 2.0 look like? Could we see 600 mh/s a year from now for the price of one coin? At the same electricity usage? How much more awesome does this thing have to be? lol
The payoff time is not exponential by adding more of them either, it will take around the same 160 days for one or for five (1500 mh/s if you're counting).

These pictures are awesome to.
Anyone wanna do a group buy? we get 500 people to buy 1 of each?
The Block Erupter USB series is the second major product of Bitfountain. Each one mines at more than 300MH/s, powered only by the USB port. See https://bitcointalksearch.org/topic/announcement-block-erupter-usb-195004 for more details.

Hashrate: >300MH/s
Power Consumption: USB Power 500mA (2.5W)
Cost Price: 1.99BTC each (min. 300 units, or 597BTC)
Your best bet to get your hands on these USB Miners early is to join a group buy. Check out the Custom hardware forum (https://bitcointalk.org/index.php?board=76.0) to join group buys to purchase units. You should always read all the terms of the group buy before committing to an order and always insists on escrow.
Happy mining,

Heh, wow. Seems like a nice buy.
No reason to buy this. It only costs $100 less than a 7950, does 300 less mh/s, and has little to no resale value.
And it wont mine litecoins well, right?
A BTCit pricey but perhaps an additional small feature in design/functionality can make it a cool trinket.
Very interesting product, but since I'm not paying for electricity, GPU remains my choice.

$220 USD is a bit much for 300Mh/s, when a 7950 is 280$+ and will easily double that.
I think it more effective than 7950
how can i buy it ?
What makes LTC mining impossible? The GPU RAM? Why is GPU RAM so expensive? Anyone have a link explaining this?

and use 100x as much power (and thus 100x higher electrical bill).

Who is supplying these in Australia ?
Kano is a developer, he got sent one to test/develop on. He's also got sent a BFL Jalapeno http://www.kano-kun.net/?p=56
If you're interested in getting one of these in Australia, check out the group buy I'm organising (link in signature). Or if you're in another country, check out one of the other group buys on posted in the Custom Hardware forum https://bitcointalk.org/index.php?board=76.0

Great concept but 300mh for that price isnt going to make it worth it.
As to earning the BTC back, one unit will pay for itself in 161 days at current difficulty levels. According to the profit calculator @ bitcoinx these should consume around 1 cent of power a day (@ 15 cents a KW)...I'd like to see a GPU match that
In 6 months, difficulty will have increased dramatically especially with all the new ASICS coming on to the market and so this device is unlikely ever to repay it's investment. Better to invest electricity in old graphics cards now which are cheap, as they might break even at least even so you're just converting electricity in bitcoins rather than making a profit.
In the case of the USB Block Erupter, it would make more sense to keep hold of your 2 BTC because you'll never get it back with this device. Maybe at 0.5 BTC there would be a chance to earn it back, but not 2 BTC.
I suppose you could mine for a month, then immediately resell the device at full price. Net profit of $30-$60.
Not really a wise investment though, lol.
