I bought the Super Clamp with double ball joint magic arm from K&F Concept and after testing it in several situations, I am very satisfied with the result.

✅ What I liked the most:
- The clamp has a wide opening and is fixed very tightly. It can be attached to tables, bars, tripods, shelves... to practically any surface.
- The magic arm with double ball joint offers great freedom of angles. It's easy to place your camera, cell phone or light exactly where you need it.
- Includes several 1/4” threads, allowing different accessories to be mounted without the need for additional adapters.
- The construction is solid, metallic, and transmits good durability. It doesn't feel like a cheap accessory.
- For my use (small mirrorless camera and also the cell phone with an LED bulb), it holds up perfectly without moving.

⚠️ Things to keep in mind:
- The load capacity is 1.5 kg, so if you plan to use it with large cameras or heavy lenses, it may be a little tight.
- When the arm is very extended, it is important to tighten the kneecaps well to prevent it from slipping with the weight.
- The screws need a little force to fully lock, especially if you adjust the position often.
