I bought three 64gb cards. Thoroughly tested with H2testw and all three failed at 7gb. Tested storage with video files. 50gb was written but when replayed the data was corrupted. They are engineered to keep writing over the first 7gb and report as successful.
The seller has offered half refund, still wants to steal from me. I contacted MasterCard and lodged dispute.
Seller has removed add from AliExpress. This was my first purchase on AliExpress so my confidence is very low now.
