I make order #1771 and paid it with 2% extra to exchange sell, and bitcoin price drop to actual price (it means u never could sell it at my request rate), you would make me a refund of this extra ?

Another problem: i received 1 board that isn't powering on, i test with molex and then with barrel plug but it doens't anything.

The other nine boards are mining flawlessly ..if you request i can show a video of it.. could you send me another one ?

Thanks
