The vendor sent me a memory of 1333Mhz when I ordered a 1600 MHz and he pretends that I have to pay the delivery to China (costs 36 USD the cheapest) to send me the correct one. Is his mistake and I have to be injured by it. I open a dispute and they want to refund me only 1/5 of the final value. Terrible customer service. Don´t recommend AVANSHARE OFFICIAL STORE.
very good
