I have had cheaper SD Cards in the past, but they almost always wound up letting me down. I made up my mind some time ago that I would stick with SanDisk and have been completely satisfied with all my cards from them ever since. This card sits in my wife's phone and is used to store all her music and pictures. It has been in & out close to a dozen times (because I like to fiddle with stuff) and as proven very durable.In case anyone wants to know, &#34;Class 10&#34; is the only way to go with these cards (until they come out with something faster), the read/write speed is well worth the few extra bucks for my needs.I also have a &#34;Class 10&#34; 64 GB in my Galaxy SIII and it's as good or better. I even got it wet (I mean soaked) and it is still working like a charm.I will definitely recommend this to anyone, and will be sticking with SanDisk for all my other devices.
