I purchased the Samsung memory card because I wanted to use it in my Samsung Galaxy S5 smartphone that supports up to 128GB external memory. After less than 2 months of usage, suddenly I lost all my pictures and videos taken. After debugging, it was determined that this Samsung memory card was bed. It's existence could not be recognized after inserting the card in other Samsung GS5 phones nor any computer.
Cons: Poor quality, Did not meet expectations
No, I would not recommend this to a friend.

After an year and a half of usage it died. There were around 20GBites of free space left when it happened. I hadn't had my pictures and videos backed up and I lost all of them! It worked perfectly for a while and a fault like this really made me sad. Neither PC, nor phone recognize it...
