I have the card for a few days. I use the card as Instaltions card for Yosemite, so as the boot drive (map). The Carte is super Schell and has let go of the problem Shapes Mac formatted. The only kretick point the card is without Aufbewarungs come "Box", but that is at EUR 6.47 vieleich not in price possible. Otherwise I can only recommend this card.
