Out of necessity, and thoroughly assessing the feature set of this camera, I purchased this on a whim instead of using our other more expensive, heavier, and harder to operate body cam for touring Zion National Park over the past weekend. While clipping on, easily powering on/off as needed, we were able to focus on ourselves living in the moment more WITHOUT having to stop, grab/position a camera, and compromise our safety on a few of the more startling areas of our hikes. That in itself, was a priceless aspect of this purchase. You can actually get much more usage time than the stated 60 mins by occasionally charging with an external battery pack; we also have a 128 GB high endurance card inserted and didn't hit this threshold. To be honest, we weren't disappointed by the footage we were able to gain to show those who couldn't come with us.So more about this "keychain" sports camera--Although I'm not a videographer, for the realm of those looking withing this price range, and not needing more expensive features like IR, this thing IS the bees knees. It's light, does offer a stable image, & has a relatively intuitive interface that it connects with reasonably well through the app. I can tell it was designed by someone that realized many of us aren't going to spend a ridiculous amount for a GoPro, when there has to be better alternate options available. Regarding operation, and what's not very clear in the listing, is that it does turn on knowingly easily in the heat of the moment, and you should be able to see the long button on the side that just a requires a squeeze until the light flashes. I do own a body cam that's more expensive than this, with a much poorer interface for the consideration of 2 of my employees who are doing property management, and I would say I would rather them wear this, as not only are there better mounting options, but easier & quicker access to those clips. This is rated a little lower in megapixels than our current, but because the files are so large on our more expensive bulkier cam, it runs out of space to store them AND the files are take longer to transfer. I've realized there is a tradeoff to everything; when it comes to 4k for the average consumer, you've reached the threshold it's actually significant in transmission and also viewing.
