**Update*** This card started to fail frequently and doesn't get detected by the camera anymore despite formatting. It almost gave up during one of our photoshoot. Don't buy higher capacity cards and lose important photos **Lesson learnt**
Fast card with amazing buffering speeds. I was using the 32gb card earlier and the buffering wasn't that great, neither was the transfer speed great. This card has increased my total burst rate on the camera by atleast 50% and also transfers really quickly to the PC. Must have.
