All you may know about sandisk class 10 16GB, what a service and what a functionality, really I was impressed. If you have used it, you also might be impressed. The one and only suggestion from me is dont buy other sdcards except sandisk. You should remember that you must buy class 10 only, because it is only the original product, there are no duplicates on this. It is so crazy and east to use it is so user friendly, service is more and easy to use. It doesnt harms our mobile or system or software. Just I will give you a live example, it its of none other than mine, it is Initially I bought a sandisk but it is not class 10. So it worked two weeks only. Ao I am suggesting you that please believe my reviews and like my reviews. Bye Bye.
