Amazon Customer "Redstorm"
When I placed this in my Galaxy S4 phone it read it right away at 29.7 GB. Which is expected to loose a few GB. I transferred file from my old card and it was done fast. Although I didn't have large files to start with. I had been looking for a large card and this one fits the bill. The other reviews helped sway my choice. I would recommend this card, so far no issues.
