I think it depends on what you are doing. If you are doing something intense enough, it works. Check out on the roofs, the guys who break into sky scraper construction sites and scale the buildings. Go Pros work perfectly for their use case: ▶ this video

For those who managed to miss the "Shanghai Tower" video from 2014 - this is what basically put this guy and his friend on the radar. An absolutely fantastic watch. Incidentally, it also helped putting some much deserved light on N'to and Worakls, whose Trauma track was used for the soundtrack. ▶ this video

Another heartstopper is this POV video of two Ukrainians illegally scaling the 650-meter Shanghai Tower while it was still under construction, which gets really nuts when they start climbing the construction crane at the very top: ▶ this video
