DO NOT BUY ANYTHING FROM -MGK.   HE'S  SCAMMED ME OUT OF 5 BTC LAST WEEK.  HE OFFERED DELIVERY OF THE PRODUCT AND IN THEY END ON THE LAST DAY WAS LOOKING FOR ESCROW.  I WANTED THE MINER SOONER THAN HE COULD DELIVER SO  I PUT DOWN A DEPOSIT AND HE WAS GOING TO SHIP.  I HAVENT HEARD WORD FROM SINCE THE DAY HE WAS SUPPOSE TO DELIVER OVER A WEEK AGO.   I LOST 5 OF WHAT WAS SUPPOSE TO COST 7BTC,   HE HAS VERY GOOD FOLLOW UP AND HE TRYS TO GAIN YOUR TRUST BY WANTING TO TALK VIA PHONE AND TEXT.  HE STARTS HIS SCAMMING BY PLAYING UP THE SCENARIO THAT HE'S  COULD BE SCAMMED A BY A BUYER RECEIVING A PACKAGE AND SAY THEY DIDNT OR SOMETHING WAS WRONG WITH THE ITEM.  DONT FALL FOR HIS SMOOTH TALK HE'S A CROOK.  HE'S BEEN QUITE ACTIVE IN THE FORUMS SO WHY HE WANTS TO RUIN HIS RAP IS BEYOND ME.
