"bought for galaxy s3"

Works awesome in my galaxy s3. Fast as could be and so much storage for music and pictures. Copys music in record time! Love the price and the product.

"Memory Card"

We use these for our Samsung Galaxy 4s phones and they are amazing because I can now take a gazillion pictures! I only wish that I could separate the pictures on the memory card into folders but that is a Samsung issue, not the memory card issue.
