Amazon Customer "lifesavr"
My pour Note 2 has been working absolutely overtime.  I just love it so much.  So I am downloading a great many pictures, audible books, and of mp3's from Amazon.  With all of these many interest of mine working over time I soon found that the 32 GB microcard was just too small.  So when Amazon had a great sale on the 64 GB ones I purchased it.  My main concerns was would it work in my phone and be fast enough to do so seamlessly.  Well that it was this 64 GB microSDXC Class 10 did.  So whatever SanDisk wants to name it, the bottom line is that it works seamlessly and now I don't get those nasty warnings telling me my memory was almost full.  It is very nice that Samsung realized the need to be able to use such larger memory cards, and the Note 2 allows this size card use without any issues at all.
