I must admit, I had not fully informed me before buying. I bought the card even at Amazon, but in the context of an action for then at the end but still too many 14,00. I am an amateur photographer and take pictures only in the RAW format. And because the problem is already known; this card can not raw, but only jpg. I had at first wondered that no image was transferred to my Tablet until I plays to the camera settings. And at some point it went well, but only with images in jpg format. Thus, the card is useless to me. But the whole handling of the card in jpg mode has not convinced me to upgrade to the PRO version. Since I stay then but in my OTG cable, with whom I offer my images via card reader on my Tablet. For those who wonder what I want to do on the tablet with RAW images, I refer to the App slingshot portfolio. Bottom line for me a waste of money.
