So. Look9ng to buy some extra memory. I have a 32g SanDisk Ultra which works just fine so am thinking about getting a 64g version. I see SanDisks on AliExpress pretty cheap. A bit worried as have seen reports that they can be knock offs. Has anyone dealt with a reputable seller on AliExpress? I can get a 64g here for between 15 and 20€ which overall is not too bad at all. But on AliExpress I can find them for between 5&6€. Any help greatly appreciated.
