What more can you say it's 4 gigs as advertised. It works in my Kodak ZX1 720P HD camera. Wish I would have known that my multi card reader wouldn't recognize it because it's a HCSD card. But, that just causes you to upgrade to high capacity card readers. Since most cards are now coming high capacity when they are anything past 2 gigs. Of course the memory business is volatile so I found this card for one dollar less, before it was delivered to me. But that's life. Then to top it off, here I am writing this review for free as if my time isn't money.
