Summary: This works with the Samsung Galaxy SIII only if you format it as FAT32. You will need a third party software to accomplish this. I personally used EaseUS Partition Manager Software (free for home users). So do not fret if you put it in the phone and it does not recognize it.
Summary: This works great with my Samsung Galaxy S3. I've been using it for few months and I have tons of movies, music, video and pictures on it, never had a problem with it.. However I bought it in July and it was 40 dollars more, wish I would have waited..But still a good product..
Summary: I had trouble formatting the SD card so my Galaxy S3 could read it, but once I got it formatted correctly (had to put it into an older phone and format it), it worked great. Have been using it for a few weeks to store all of my music and have had no issues.
Summary: works great, only thing cheap about it is the thumb drive they give you, mine fell apart, but you can put it back together easily. Would of gave it 5 stars if the thumbdrive was better quality.
Summary: I am using thison my Motorola Xoom. It came formatted as exFAT and worked without any issues. I have since formatted it as ext4 (needed some additional hacks). Although the item description says 'Retail packaging with Komputerbay SDXC USB reader", the item came without any USB reader (with only the SD adapter).
