I use this for downloading 16gb compact flash cards to Lightroom from my 7D. Lightroom recognizes the card as a device, which is nice rather than thinking it's a typical removeable drive like some do. Downloads reasonably quickly especially considering I'm still on USB 2.0. It's well built and not very big so I have no concerns about taking it on a trip. I'm using Delkin cards with it so I expected it to work, but it also read a Kingston card that none of my other readers would. So far it's the best card reader I've used.
