So far so good. installed it on a Nextbook tablet running Windows 8. After upgrading to Windows 10 I was asked if I wanted the tablet to use the micro SD as storage for future apps and files so I got that first. I've changed and so far I'm happy. But actually I haven't given it a task like big file/transfer yet. Considering I paid less than $100 for a tablet (Walmart) this gives me a cheap memory boost.
