This is the second card I've purchased of this exact model.  The first one I had went bad after about 8 months.  To be fair, I had it in a rooted Galaxy S3 with CM10.1 loaded on it.  So it's possible that something in the experimental firmware messed up the card.I'm back on the stock rom now due to issues with 4G LTE.  I'm not even rooted anymore.  So I'm hoping that the card remains solid this time.  Everyone else seems to love it so I'm hoping serves me well for a long time.So far... So good...
