I've already said everything in the title, but I will add that I might have had to read all the comments before buying this card associated with an Eye-Fi card - mobie-8. At the connection level, it hangs then answers, in fact the symptom seems to be recurring to other owners of the same product. Personally, I think it's a power problem of the card that must be supplied with current continuously. I wanted to believe it, too bad, so call back to the Amazon service.
