I have the smart card ordered from Amazon Prime, because this was the shortest delivery time, the delivery went smoothly and I was totally satisfied. After the first 60 photos I transferred the pictures to my computer 2 photos were totally damaged When reinserting the card I had to reformat the camera. The next time I had to reformat the camera again but since then nothing works !!!! As other reviews also be very negative I suppose that in this chip, the whole series is faulty.
