On both devices, there is a "thumbs up" from me. The card is definitely fast enough to all tasks in Smartphone (move files, high-resolution photos or videos etc ... save) to pass well. Also in the video camera she showed no weaknesses.
Compared I have it with two Micro SD cards from SanDisk, a "Extreme" and "Ultra". Compared to the "Extreme" which Qumox is slightly faster. The "Ultra" is at an advantage when it comes to huge files (Ultra HD or Full HD video movies with very high data rate), as it shows its strengths. In smartphone but had this advantage in, even when the timing of storing a picture after recording the phone.
Conclusion: So if you're looking for a good quality and fast card for his smartphone or tablet, then you are right here! Yes, even for the most amateur photographers, this card is more than just a look. So you have to look not always known (and expensive) names and buy there, here you really get a lot for your money!
