The card itself is well made and has no optical defects. I had used the card for a while in my Samsung DV300F compact camera, and a tablet. There, it provided very good services without any failures.
Now I wanted to use this card in my Samsung NX3000 system camera. Photos folded so without problems (normal shooting, no series photos).
Problems then appeared but on when recording the video with this camera. The videos juddered all pretty much at the PC and were thus simply ugly. It seems that not process the card fast enough data. With a Samsung Pro card now everything runs smoothly. The Pro card is twice as expensive but also a lot faster!
I have nevertheless awarded full rating points, as the card is very good in itself. For larger amounts of data, it is now time to slow, but therefore there are also different types of cards.
Anyone who wants to use the card in his phone or tablet, can strike without hesitation. If you want to record Full HD video or something similar so that, should rather resort to a faster card.
