The flexible helmet holders from K&F Concept are the perfect solution for me when it comes to securely attaching my action cam to the helmet. In contrast to the classic GoPro feet, they have a significantly larger adhesive surface, which adapts perfectly to curved surfaces thanks to the flexible design. This gives you a great feeling of safety, especially when riding a motorcycle or on a mountain bike. As usual from K&F Concept, the workmanship is top notch. I've already used a few of the brand's products and have never been disappointed — this once again confirms my impression. The pads stick firmly and reliably, yet they can be attached without having to experiment forever. I also find it particularly practical that 3 pieces are included in the set. This allows you to prepare several helmets or surfaces or simply have a replacement ready. This is ideal, especially if you frequently switch between different attachments or cams. For me, the price-performance ratio is absolutely unbeatable: For the money, you get high-quality, which you absolutely need in the action sector. After all, no one wants to risk the camera falling off while driving. Personally, I find this solution even better than the classic GoPro mounts — more stable, more secure and simply more sophisticated. For me, it's a very clear 5-star product.
