Really I faced a big problem when suddenly damaged my card. I suggests everyone please don't bought this card it will be damaged after some years. But one thing good of this card it is so fast and valuable from ither chipest memory cards( samsung, sony) . SanDisk ultraSd card's file transferring speed is so fast 50/s, that is the awesome features of this card. Recently I bought 16gb card but that damaged after 7 months.
