I bought this little item a month back when I decided I needed more cards for my Jetbook. I've read reviews that it tore etc, and all I can say is, you may have been trying to shove too much into this. The plastic sleeves are the same as what your picture holders in a wallet are made of, and is actually pretty strong. I have mini SDs in their holders, and several 256 cards with my books on them. Nothing has ripped and it holds 16 cards very neatly. But it will NOT fit anything larger than a SD card. No CF cards or anything like that. So, if its used as it is meant to be, this is actually one heck of a deal.
