Pros: Cheap

Cons: Extremely Poor Quality

Overall Review: All three out of three cards purchased have now failed. The first failed just outside the 30 day return window. The second made it about 6 months, and the third has now failed at about 1 year. No device will recognize them, so there is no chance to reformat and get them working again. They were used in 3 different, name brand Mp3 players, so there is no chance that the devices killed them. They were only written to a couple of times, so there is no chance the life of the memory cells were exceeded. To have one out of three fail is manageable, but to now have all three fail means that they are of seriously poor quality. Definitely not worth the savings. Recommend sticking with better known brands that have a good track record.
