I was looking for a reliable POV solution for my [GoPro/Insta360/DJI action cam] because the manufacturer's original accessories were simply too expensive for me. The neck mount from K&F Concept impressed me based on the specifications, and I can confirm after the initial tests: That was absolutely the right decision! The workmanship is excellent for this price. The flexible silicone neck construction is skin-friendly and feels very high-quality. The central mechanism with the air cushion does what it promises: Even on longer hikes, you hardly feel any pressure or fatigue in the neck area, which increases comfort enormously. Stability during sport was particularly important to me. When riding MTB on trails, the combination of the sturdy neck section and the optional chest strap provides surprisingly quiet material. The recordings are far less shaky than I would have expected from a mount of this type. The quick-release fastener is a real highlight: It holds the camera securely, but allows it to be removed in a flash with just the push of a button. Functionality and compatibility are identical to the much more expensive original products, and the ability to quickly switch the camera to portrait mode thanks to the integrated rotation function is also worth its weight in gold for social media vlogs. Conclusion: Significantly cheaper than the original with the same function and good workmanship. Anyone looking for a hands-free, stable and convenient POV solution — whether for relaxed vlogs or sporty MTB tours — should go for it. An absolutely essential accessory and a clear 5-star recommendation!
