Two cards were ok but the third was faulty. My software could not format it as the file table was absent and it could not be created. Having contacted the seller they suggested I format it fat32. - obviously not having read my messages. Poor service. Due to the prevarication it is not possible to open a dispute. i wonder if I'm wasting my time writing this as it will only be read by the software and then junked.
Very good people is good quality fast delivery. I am very satisfied with the seller it delivers what it promises.
