It should be first on your list!  If you have an action camera with you, it normally configures itself once you power it on and the time it needs to be ready for use depend on the speed of the micro SD card you plugged on it. I used the other micro SD cards on it too but the Xtreem Micro SDXC UHS-II U3 has the fastest time for boot as well as in taking photos and videos. This was certainly a good addition to my action camera. <Read more>
