Also, I am afraid to say that your price is too high. Like, by 150 Euros.

Currently, I have bought and am waiting for 3x Antminer U1, 1.6GH/s overclockable to 2.2 GH/s.
I got them for around £35 each plus shipping.
With just two of these overclocked or three at normal running I can achieve your GH/s with the same power drain and a much lower cost.

 Plus, your product is too big to fit on most USB hubs, while Antminers are much thinner and no heatsink.

This is not economically viable and is a ridiculous amount to spend for such a small GH/s. Reduce your price to €85 and we can start talking.
