If you are not in high winds, it allows you to get easier pictures when in mode 1 speed and cruising around at the same altitude with little effort

It works fairly well, as others have mentioned, it is very low resolution, so don't expect stellar pictures / video

It can already be hard enough to get in position for a good picture, but to then have to remove your hand from the controls to punch a rather small button on your phone screen, makes even more difficult
