The fact remains, that when you mine, you essentially transform energy (the watts) into information, it's simple physics. Information is energy. Being able to hash at 3.5Kh/s for 10W just doesn't seem right, you're near 100% efficiency. And don't get me wrong, but looking at the pictures of the miner, it doesn't look like much...

If I were you, I'd produce 1000 and run them myself and just dump whatever I mine to make a shit ton of $$$$.

If someone trusted on here confirms that your miner does what you say it does, then I'll be the first to order 10 from you. But until then, this is a scam in my books.
