Kind of what I expected. Got this as it was stated to be designed for use with tablets/phones for better app performance. I wasn't sure how it could do so compared with other cards of the same type and class. I also don't find it to be any faster with apps and still has slightly longer loading times compared to using internal storage on devices (as most other cards do). But it's still decent SanDisk quality, just wish it was a little quicker as it tries to say.
