I don't understand the purpose of these USB miners.
They will never make ROI, plus don't they have to be controlled by a computer?
And how much power does that consume?

in fact, this is the only unit i have owned that make ROI.. not in mining, trading the hardware. selling these units was a great deal
It is also 15BTC for 500 units.
I have actually heard from a lot of people making good money by selling USB miners.
I personally don't think it is a good move for me.
If I had 15BTC to invest it would be on other things
