I bought this for a Galaxy Note 8.0, and while it functions properly, it is completely useless for my tablet. I can't put movies or books on it, because they are streamed from Google Play, and i can't put apps on it because that is not allowed. Why do they put a $&@?!$@& micro sd slot on a tablet that can't use it for anything but backups- backups i might add that are already in the cloud. Amazon did a great job delivering it, which was a bright spot in the realization that i spent 25 dollars on a chip that is going to do a better job cleaning the dirt out of my grout than helping the memory on my tablet.
