Summary: Got this to add capacity to a Clip+ music player. About the 6th or 7th month, a few music files became corrupted. As time went by more and more files became corrupted, until I stopped using this memory card. With this card installed, the music player could only run about 6 hours on a full charge.
Pros: Adapter works fine.
Cons: After a few months files became corrupted. Took a lot of power.
Summary: Picked this up in November 2012 for 11.99 with a 5 dollar rebate. Put it in my tablet and it worked great for about 9 months. One day I turned the tablet on and it suddenly wouldn't mount. Apparently this is pretty common based on other reviews.
