Speed: The card outperforms loose MicroSDs normal, but does not reach the specified speed. On mobile, the speed is only slightly faster than normal cards (though FOR SMARTPHONES DESIGNED! Removed from the packaging)
My problem: I have the map now used to my two androids, but in both the same problem: Android displays the message: "Card was unexpectedly removed." I have now gone through Windows 7 checks for errors and the card so far is working properly. Whether this error now system is on Android, or at the card I can not say, but I think of the card, which does not flow into my review.
Conclusion: Overall, a "better than average" card which is very suitable for transfers from the PC to the card, but want to let only the cell phone, then you can also save the money for it and buy a normal MicroSD.
Thus: 4 stars
Update: card was in the phone, she suddenly broke. All my data on it are now gone and I get only 250 euros with a professional company back. VERY BAD
This only: 2 Stars
Update: Have the card again in the PC plugged and at once she went back !! Unfortunately, it sometimes does not work with my Samsung Media Player (see above).
So again 3 star, BUT I WOULD THIS MAP IMPORTANT DATES TRUST
