So far, so good. Did a video with them at a concert for the first time last week and they wrote quickly. I turned the camera off and on between a song or two and never had to wait to start recording again. I took several continuous shots and didn't have to wait. Used in Sony RX100M3 set to AVCHD @60p 28M. I'm happy! All my photos and videos were good, there were no problems with the cards.
