A card that failing to predict the future work very well so far

A card that failing to predict the future works very well until now. I installed the card in my smartphone (Samsung Galaxy Ace 2) and I have had no concern over file transfer speeds are impressive and this without even using USB 3.0 port. I have no complaints about this card, she just me perfectly, over the adapter is very handy if you want to insert a second card in your camera / phone to continue taking photos or videos while one viewing or working on those already taken. Only one question remains in my mind, whether the card and the adapter will take over time.
