    The employee in store was super helpful assiting me in finding and getting the correct card for my camera. This card was it. Unfortunately it was not in stock in store but they 2 day shipped it to my house for free. So far i have a ton of pictures on it and its been working great.

    I am the proud owner of a Marantz Compact Flash Audio Recorder and this memory card made even my archive recordings even better! Those folks to believe all "1"'s and "0"'s are equal, I say try one of these SanDisk Extreme's in your recording gear or older camera and watch/listen to what happens! Take that - You Vinyl and Tape guys! This thing can outperform an actual hard disk of similar size by 20%!

    In the future I will continue to use this with my cameras that use this type of card. It works well with my Olympus 620, Canon 50d and Canon 5D3.

    I went to another store to try and find one in spur of the moment and it was way more. I came in for a 32gb and they showed me this one which was double what I needed for a small fraction of the price bump. Works great with my camera and allows for a ton of shots with quick captures like burst mode.

    I bought this to "retro-mod" a 4th Generation iPod Classic. Went with SanDisk because of their reliability. I've used other CF cards in the past the only brand that I has yet to fail on me is SanDisk. Since I don't won't to be re-opening this iPod case and disassemble it again because of a failed CF Card, I went this way. Plus, they had an awesome sale on this as was $20 less than competitors. I only buy my computers/electronics from BestBuy - Amazon can't beat them!

    I don't remember which camera has this card right now. I use these cards for Canon DSLR cameras. I have old 40D and 5D models that I think are just as good as the newer models in terms of ease of use. They need this kind of card, and I'm always on the lookout for more of these cards. I'm happy that Best Buy carries them. SanDisk is a reputable maker.
