Works like a charm.  I originally thought this was expensive and bought an off brand card, which ended up being junk.  I returned it, spent the extra $15 on this card and it is awesome.  I have it in a Samsung Galaxy Tab 3 8.0 (SMT310), and watch movies, read books (pdf), and listen to music on it.  Since I travel a lot I will end up buying a couple of these, that way I won't even need to take a full size laptop with me.
