I'm not a professional videographer, but I will say that this K&F Concept Neck Phone Holder sure makes it easier for me to make my product review videos. I tried a different brand neck phone holder a couple of months ago that turned out to be utterly disappointing. It can't hold a candle to this this one when it comes to comfort, flexibility, stability, and ease of use. The K&F phone holder is very lightweight and super flexible. As you can see in the video, I was able to twist the neckpiece into a figure eight and back with no damage to the unit whatsoever. The neckpiece is soft and easy on the neck, and the chest mount has a soft air-filled silicone pad that's comfortable against the chest. The chest strap adjusts to accommodate larger body types. I am a 2X plus size woman, and it fits comfortably. I think the chest strap is the game changer when it comes to keeping your phone stable while recording. Of course, you can't expect perfection simply because of the nature of the beast (as the old saying goes) because it's impossible to keep your body completely still for any length of time, unlike say, a tripod. After all, you have to breathe, right? With a little practice and learning to move smoothly while recording, though, I believe the quality of my product review videos is improving. Riding a bike or hiking along a trail would obviously be more challenging, but I think this neck phone holder is a great inexpensive option, especially when you consider all the features. Numerous POVs (points of view) or angles can be achieved with the 360° rotating phone mount, the 180° rotating chest mount (90° left or right), and the 180° rotating and jointed phone mount bracket. The only thing I found to be negative about this neck phone holder is the clip-on feature. I can barely fit my 6.7" phone in it, and it hurts my fingers trying to pry the clips open. I used a smaller 6" phone with a fairly slim case for the video, and I still had a hard time getting it between the clips. Nevertheless, I still use the clip-on holder with caution, hoping my phone won't pop out. I think they need to be wider and adjust out further for phones that can't be secured by the magnet. Just a thought, but why aren't these clip-on phone holders made with perhaps some small finger holds on each side of the clips that make them easier to pull? I also think the chest mount should be a lot wider, which I think would make the phone mount much more stable. At least, that's how I would design them. (Your welcome, K&P.
