  • Review: Fast file storage by my Canon PowerShot cameras -- Extreme III is the best I've found. Great price, fast delivery, top vendor!

  • Review: I use this card in my Canon Powershot SX 1 and it works very well. I take mostly nature shots, usually outside and I need a card with a fast write speed. I especially like to use the "continuous" shooting feature at 3-4 fps. The images are clear and it works well in cold temperatures and on damp days.

  • Review: Got this to replace my Lexar Professional 133x 1GB card. Seems a little faster and much more space for my Nikon D80 pics.

  • Review: My research indicated this high-performance card would shorten the time it takes between shots. Mine doesn't. It does increase the speed to download from the card to my hard drive, so for that I guess it was worth it.

  • Review: I Haven't used the card much since it arrived, but it seems to be faster than a generic card when transferring.
