This is 100% Genuine Class 10 Memory Card For SanDisk. Our mobile phones get taken everywhere with us and with the recent development of camera and smart phones they are no longer used simply for making calls but are also used for capturing photos and videos and parties or events where you may have forgotten or not wanted to be burdened with a camera, and also for storing and listening to music and playing games. Often phones can have very small internal capacities and with all the above applications, you may find yourself running out of space and no longer able to store your desired files, hence missing that momentous photo or video or being unable to listen to that fantastic new music track. SanDisk microSDHCTM (microSDTM) mobile memory cards can quickly solve such problems and are the most popular and best way to expand your storage options and carry your music, videos, photos, games, files and applications on supported phones.
