Summary: When you need a lot of songs and data, you need to get a better memory card. Tested the card on a nokia phone and it was working superbly. No lag at all. This card is meant to be used on phones. When I used it on my tablet (iball i9702) there was a little lag couple of times. But if you intend to put it in your phones, nothing like it. Look no further and just buy it.
Summary: Perfect for android smartphones. Its a price worth product and the performance is outstanding!!! There is no other option cheaper and better than this. So it is my advice go and buy this product.
