Three 64gb micro SDXC memory cards I purchased on eBay are fakes. Files are corrupted on your devices. When tested they only have 7.2gb useable space. Missing the color-shift technology badge that's on originals (see video at Kingston.com). No UPC barcode on packaging. All 3 have same serial numbers. I already contacted Kingston and they said they'll check out the pics I sent and let me know what their findings are.
