I don't think I could give these away for free if I wanted to.
40-50 Watts for these guys is worst than 3 of my energy saving lightbulbs, and is supposed to run 24 hours a day.
I still don't know what the purpose of these particular miners are yet. Not enough hash, not enough power efficiency, and at a high pricetag($2.40 per GH). Can't scale large enough to be profitable, can't really run without more than several, and need a host computer on at all times.
Guess, novelty item, maybe.
