I got this for new phone Nokia 525 and this card works at its best. I'm very pleased with it! I have stored some 180 mp3 songs and 4 movies and still loads of space for pictures, specially for Nokia 525 with 5mp camera.
Nothing much you can say about an SD card. You put it in your phone and off you go. The adapter was dreadful to use. It was so fiddly to use and the card kept falling out of it. They need to improve that.
