I had been considering this type of mount for some time but was quite dubious as to how well it would work. However, I was pleasantly surprised as to how stable this neck mount is. I expected a degree of camera shake, but it all honesty, I did not detect any. The camera remained stable when walking and allowed some moving and adjusting whilst it being noticeable on the recording.The mount is really easy to use. Once the camera was mounted (Osmo Action 5 Pro with a magnetic mount one-click solution attached to the claw mount) it was just a question of adjusting the angle and turning it on. The mount gave a real POV recording and wherever I turned the camera turned with me. There was enough space for me to be able to hold the camera for specifc shots so I could check the framing.As far as functionality is concerned I was really impressed not just by how easy it is to use but also how natural filming becomes. I even forgot that I was wearing it to the extent that I was still wearing it long after filming had finished.It is the essential accessory that I didn't know that I need but now that I have it I will keep using it.The build quality is great - as I have learnt to expect from K&F. This is a trustworthy brand that really does produce high quality accessories. Just as importantly, it is a good price for what you get.I have to say, I wish that I had discovered this earlier - if you are thinking of buying one, stop thinking and buy it. Highly recommended.
