Review on Adapter Android Smartphones Tablets Nintendo Switch by Richard Surveh

20MB read, 10MB write, too slow for either of my two dash cams this memory has been classified for, works in my S9 phone. Wouldn't go as cheap next time but works with 1 of 2 of my car cams and S9s for now. Update: Very slow, the files on my dashcam are corrupt and unreadable. I need to upgrade the memory, the specs for this card fall more optimistic than the actual advertised speed and performance. Garbage.
