This 11-inch magic arm from K&F Concept has exceeded my expectations. It is robust, compact and very easy to place on any support thanks to its super clamp, which adapts to both flat surfaces and tubes. The clamp holds firmly without damaging thanks to the non-slip rubber coating. The central locking system is really effective. With a single turn, both ends of the arm and the spherical heads are fixed at the same time, allowing it to be adjusted quickly and kept in the desired position without unwanted movements. It offers great freedom of angles with 360° rotation and 90° tilting, ideal for placing lights, microphones or external monitors in recordings. The set is completely metallic, with quality finishes and 1/4” and 3/8” screws that make it compatible with multiple accessories. Despite its light weight, it holds up to 2 kg. In my case, I use it with a small LED light and an external monitor, and it stays stable for hours without sagging. A very useful tool for shooting and photography, easy to carry and that adds a lot of flexibility to the assembly of equipment. Highly recommended if you are looking for a reliable, well-built and precisely responsive accessory. 5 stars.
