@ $35 and 280mh/s this device would return the investment in 26 days.
That's a pretty good deal. I'll buy a few the day you release them, as long as they take <1.5 months to return.
I couldn't get my head around those people buying the 10gh/s block eruptor boards for 50btc (roughly $5,500). Those would take over 119 days to pay for themselves, and the hash rate on the network has been increasing, devaluing the reward for mined work by 15%+ in the last month. That's a lot of incurred debt for a long time.
These USB sticks are just plain cool though.
