Have purchased in 2014 for the Galaxy Note 10.1, this memory card. You will promptly recognize (everything else would be a shame when combining Samsung - Samsung) and working properly. The normal retail packaging is good to open (already seen much worse). The adapter I can not comment because I have purchased the version without using an adapter. Samsung sold so different versions of microSD card: On the one hand "EVO" (= orange) and "PRO" = (silver layout). For normal standard users who want to store only files, such as PDF files, music, videos, etc., this card will do just fine, you can charge for the PRO version to save my opinion. If you want to move only the best will often large files or for his art baby of course, the extra charge for higher transmission speeds can be quite worthwhile.
In what format the card was formatted, I have not checked, since I really want to use only a memory in the score. It worked right away and so I was not concerned with the technical events.
Edit: 5 minutes after publishing of this review, I learned by chance that Samsung also offers a Class 6 series. These then have a blue layout and the "slowest" cards among the three series. These cards are sufficient for simple applications easily, but the price differences are very small (with 32 GB currently 2 euros for EVO).
