Owner Reviews, Ratings, Comments and Criticism
I recently purchased one of these compact flash cards from Amazon to use with my Canon EOS 7D. Mainly I purchased this card because of its capacity and speed and am not at all disappointed. Honestly this is one of the fastest flash cards I've seen and can easily handle anything my 7D throws at it. For the 7D at least, 18mp RAW files using high-speed continuous mode were not a problem. Ships with a waterproof case that seems a bit gimmicky. Couldn't help but wonder how much cheaper the card would've been without the case. Although I haven't needed to try it, I hear their customer service is impeccable. You may be able to find a less expensive card with the same size and speed as I think the durability ratings contribute to the price and may be impractical. That being said, this is a fine quality card and certainly will not disappoint.
