I do not look at the card's speed here. They are depending on the equipment tipped times better and sometimes worse. (Have an old notebook to new rapid system camera with continuous shooting mode in use.) A criterion for my review is the convenience in use and here I can say, so far it has considered subjectively not slowed me and was in the offices of my devices also easily recognized. As another card was used, I have now bought a second. These runs without problems to my satisfaction. Therefore, there is of me 5 stars.
