i give this memory card a 5 star because it works like a charm easy to use plug and play. The packaging is easy to open so you don't have to worry about damaging the card itself . Slipped it right in my Samsung galaxy S-3 maxing out the card slot with this SanDisk 64gb but it only displays (59.47gb) its stable and fast works really good. didn't have to format anything or do any extra steps to use it. i recommend this to everyone
