I PURCHASED A MOTHERBOARD FROM ALIEXPRESS . RECIEVED IT , INSTALLED IT , BOARD WAS DEFECTIVE , NOT WORKING , I ASKED ALIEXPRESS FOR A REPLACMENT BOARD OR A REFUND , THEY DENIED A REFUND AND A REPLACMENT , I HAVE BEEN RIPED OFF OF $ 337.27 DOLLARS AND STUCK WITH A DEFECTIVE BOARD THAT DOES NOT WORK , ALIEXPRESS IS ONE OF THE MOST DISHONEST ONLINE SHOPING TO DEAL WITH ,, User's recommendation: DO NOT BUY ANY THING FROM ALIEXPRESS , VERY DISHONEST.
