To begin, I am not that knowledgeable in tech matters so when I received a new Galaxy Note 2 as a gift and decided to add storage I read some reviews on the SD cards and was reading about the compatibility of the 64 GB cards (exFAT or Fat? I guess the exFAT was a successful diet), I was concerned somewhat but I ordered this one anyway and this is what my experience was. I added some music and videos onto the card using my Apple Macbook Air with no problems and then inserted it into the Note 2 with no problems and it immediately loaded everything with no problems. I have since taken it out and added some more music to it and it is working perfectly. I did not reformat or anything like that which was a great relief. Although I have only used this item for a week now with issue which means something could go wrong in the future, I would give it more than 5 stars if possible because it was easy for someone like me. I know I used the phrase no problems multiple times but when you are my age and things go smoothly with no problems it is very good.
