I use it for funjumps. Very happy. The camera shoot flawlessly. Internal memory is more than enough for a couple of days. It was around 55 percent of the charge left of the main block after 5 jumps( 2.7K and I filmed only freefall. No under canopy ride). So possibly last for the whole jumping day. Especially like the strong Vibro function for on/off. And obviously no overheating problem at 14K feet). Here are some shot test clips.
