I picked up the K&F Concept Super Clamp (MS13) mainly to help with mounting my camera and lights in my pretty cramped workspace. Out of the box, you get the clamp, a dual ballhead magic arm, a GoPro adapter, and a phone holder. The first thing I noticed was how solid everything feels—it's made from aluminium, so it doesn’t seem like it’ll break anytime soon.

What I really like is how flexible this thing is. The magic arm rotates in every direction, and you can adjust all the joints with one thumbscrew, which saves a lot of time. The clamp opens wide enough to grab onto just about anything—I’ve used it on my desk, a tripod, and even my bike handlebars for a test ride (that was a bit of a stretch, but it held up).

There are several 1/4" threads on both the clamp and the arm, so you can attach all sorts of gear. The anti-scratch pads are a nice touch—they keep things from slipping and don’t damage surfaces. Sometimes I just use the clamp or the arm on their own, depending on what I’m setting up.

In terms of performance, it’s been super reliable. I’ve used it with my iPhone 15 Pro Max, a GoPro Hero 11, and my Sony a6700 with a Sigma 18-50mm lens, and it’s held everything steady. The quick-release is handy, though I did notice that if you clamp it onto a really smooth surface, it can slip a bit. Also, if there’s a lot of vibration (like on a bike), the thumbscrew might loosen, so maybe not the best for action shots unless you add some threadlock.

Pros:
Feels sturdy and well-made
Holds onto almost anything (even my door!)
Super adjustable magic arm
Lots of mounting options and accessories
Good value for what you get

Cons:
Grip isn’t perfect on very smooth surfaces
Thumbscrew can loosen if there’s a lot of movement

Overall, I’m happy with it. It’s compact, lightweight (about 220g), and has made my setup way more flexible. I’ll definitely keep it in my kit for future shoots.
