If you're using mined coin or stuff you bought before April it might be worth it, but I pulled out of a group buy as I really couldn't see it panning out with newly bought coin. No way are they worth $260 and if you don't get them fast I don't think they'll even pay for themselves. Could be wrong - but if you plug in the predicted difficulties for July/August in your calculations you ain't got long to make your money back.

Looks like a 12 month ROI in BTC terms, using 20% per month increase in network hash rate.

They're only guaranteed for 5 months (whatever a guarantee means).  I'm a newb so I don't fully understand difficulty but this blog - http://organofcorti.blogspot.ca/2013/04/914-asic-earnings-23-april-2013.html seem to be getting positive vibes on here and there's other threads too talking about 64 Million difficulty for August.  If people want to mine with something that only does Mh/s now, I think they'd  be better off buying dual 7950's *this weekend* and hashing now.  Then you can convert to Litecoin in the summer or sell off. Usb eruptor's ain't going to be worth diddley-shit come September.

The ROI on a 3xx Mh unit is 6 months, but in 6 months the DIFF level will turn the ROI into 2 years, who pays $260 for these things?

I just wish I thought of this because they are making millions and in exactly 30 days people are going to be screaming because they realize they will like never get their money back.


When they can be had for $70 let me know

Go do the math and figure out when exactly they become 'unprofitable' to run at 1.5 Watt!
Sure they are not cheap, but considering that I can run 1 of them for 800 hours for $0.05 they will continue paying for themselves for years even with crazy diff increase, and that is not accounting for possible (probable) increase in bitcoin value. + You get a kick-ass conversation starter and a piece of history!

Sure - if you've got spare cash and you want a souvenir, or if you paid a lot less for your BTC than the current rate then it might be worth it - otherwise, forget it. 1.99BTC at current rates is a crazy rip-off price for a 300 Mh/s device - I'd love to see the Bill of Sale for the components.

In the near future these devices will be as cool as floppy disks today and great fun to show the kids how we did it. Your math on the other hand adds up as soon as one figures out how to use an usb eruptor without a pc that runs 24/7. Compared to a small GPU with similar hashrate it´s a fun alternative of course.

I did the math, using cost of electricity at ZERO, and the cost of the Miner at 2 BTC you will get your money back in 172 days if the DIFF does not change.
If the diff goes up at the anticpated rate, you will get your money back in over a year.

If you took those same two BTC and added 1 more BTC and bought a 5GH unit from BFL and they took 4 months to get it to you, you would still get your money back faster.

I bleieve he was reffering to the fact that you have to hae a pc running using electrity to use these. So .1watts in not what you will trully be using since your computer will never go to sleep. Even a mad range laptop uses like 90w I think
