WORST SELLER EVER. DO NOT BUYT FROM THIS SELLER OR ALIEXPRESS. Bought 6 RX cards all had heating issues and wrong BIOS installed. Seller told me to get them repaired and he would pay costs. Only 3 cards were repairable. I asked for half my money back but seller offered a lousy $140. Raised a dispute with Aliexpress, they accepted the evidence cards were faulty, but the seller would budge. I REFUSED his offer in the twice but somehow AliExpress ACCEPTED anyway and closed the dispute. Last night another of his cards failed. I am now stuck with 4 dead cards. I spent $742 for the cards plus $150 with the local repairer at a total $892 for 2working 2nd hand RX560s. I have still not seen even the lousy $140 offered by the seller. This entire process has been a complete SCAM on the part of the seller and complete JOKE as handled by ALIEXPRESS. I WILL NEVER BUY FROM ALIEXPRESSS AGAIN. Save yourself pain and money and DO NOT BUY FROM 'HUAPU STORE' or ALIEXPRESS.
