I have lot of these at work 8GB, 16GB, 32GB, 64GB. Though I haven't done real speed tests on these, but these have been reliable all along. Used in music players, cameras, laptop SD Cards. These do sell at a little bit of premium because of their Class 10 tag, but I would buy these any day, if I need these for cameras/laptop extra storage. But if you are using these for music players, you are good even with Class 2 cards.
