Summary: Item did not work no matter what card I used. I called support not much help the assistant told me everything that I already tried on my own very disappointed , so I'm sure you'll understand what my next move was? Yes in deed; happily returned to store.
Excerpt: I've had a few card readers and this one by far is the best I've ever used.<br /><br />I have a Canon Powershot SX40 HS and I often use CHDK for RAW photos. Those images have a fairly large file size and so I own a couple of high capacity cards...a 32GB and a 64GB card.
Pros: Fast Transfer, Lightweight, Long Cable, Reliable
