The card works just fine, no problems at all.
For those of you who are wondering if this is actually a Class4 card, then the answer is no - the picture is deceiving, it's a class 2 card.
Good product does what it says on the tin. Excellent service again by play, only gripe is the excess delivery packaging. For something so small does it really need to be delivered in the same size box that I receive my DVD's in?
I would have given it 5stars if you were to get an USB adaptor etc, but for the price I am happy, works fine haven't noticed any difference in my phones performance.
