I bought the SanDisk Extreme to maybe even get a little more speed in the sequential shots with combined JPEG, and RAW mode in my Panasonic digicam G2, but unfortunately no advantage has brought to my other SanDisk 32GB Ultra card. No problem the card but the camera. But perhaps because of the price difference between Ultra and Extreme cards anyway is quite high also interesting for someone else yet. Adapter works well and the austerity package, I find a good solution. Less waste is good.
