This is a pretty great little clamp. The entire thing is made of metal, except for the rubber pads on the clamp jaws and the camera mount tightening dials.

This has the standard magic arm layout with a tightening screw in the middle that clamps all three rotation points.

The whole thing is well made. The machining is precise and nothing feels sloppy or cheap.

I bought this a month ago, and although I haven’t needed it often, when I did need an extra “hand”, this K&F Concept 6" Magic Arm has been really useful. It's really well made and sturdy. I do wish it had a clamp on either end, though so it could hold a small reflector in place. I think I will be buying an additional clamp. However, it is great for holding my Smallrig light in just the right position. The only regret I have is that I bought the 6” arm when I should have bought the 9.8” arm (or longer). You may not need it often, but you’ll be glad of it when you do.

I bought the mount to mount my 360° camera on the bike.

The mount is very good and of high quality, which I expected at the price. The mechanism works sensitively using a single dial. This allows the camera to be aligned in one step. The claw can be tightened properly on the bike frame, everything held securely on tour. The bottom line is that I can only recommend the mount. There is nothing to complain about when it comes to quality, robustness and handling.

The arm and the clamp perform their function perfectly. By size, I see them suitable for an Atomos-type monitor, a smartphone, LED, a flash and of course small mirrorless cameras, as well as other accessories.
The adjustment systems for both the clamp and the arm are easy to operate in practically any position, and during the time I have been using them they have been comfortable.
The clamp is capable of supporting up to two kilos perfectly and thanks to its 1/4" and 3/8" threads it is compatible with an endless number of photographic accessories. The set does its job and feels good quality, with excellent finishes, and with the versatility of being able to use both the clamp and the arm separately.
Suitable for carrying an action camera attached to your camera to record yourself in the first person, for macro photography to attach an LED light to the tripod, portrait sessions where you want to place a Flash on a railing or branch, a light on a shelf, table, are some of the many examples that I can think of, that can be done with this set.
I am happy with this K&F product and recommend its purchase.

I received the following article from Amazon to test and describe my personal experiences with it below.

I don’t usually over hype camera accessories because they are normally hit or miss, but I will say this Magic Arm deserves a solid 5-star shoutout. I’ve been experimenting with different ways to capture unique angles for my bike videos, and this little arm paired with the super clamp has completely changed the game for me. I clamp it right onto my bike frame — usually the handlebars or seat post — and it stays rock solid even when I’m hitting bumps, turning corners, or just cruising around.

Before this, I tried a few cheaper versions from places like Temu (you know the ones, they look fine in the pics), but they were always either too flimsy, wobbly, or the joints wouldn’t stay put no matter how tight I cranked them. It got to the point where I’d spend more time adjusting the thing than actually filming. But the moment I unboxed this arm, I could already feel it was in a different league. The metal construction is solid — like surprisingly solid — and it has just the right amount of weight to feel trustworthy without being too bulky to mount on moving gear like a bike.

The joints on the arm tighten down really well and actually stay in the position you put them, which is huge for action-style filming. I’ve mounted an phone mount, a small light, even a little field monitor for more composed shots — no sagging, no slow slipping out of position. Everything just stays where I want it. The locking knob feels beefy and smooth, and those orange accents make the control points easy to spot when I’m adjusting things on the fly.

The clamp is equally impressive — it grips super tight onto most things, even tricky shaped objects. This is perfect for bikes or tripod and doesn’t require me to over-torque it to feel secure. In short: this thing is solid, versatile, and absolutely worth the money — especially if, like me, you’ve wasted a bit of time and cash on cheaper knockoffs that just don’t deliver. I’ll probably be picking up a second one soon.

I hope this review helps someone out.

Feels sturdy and well-made, with a solid, high-quality finish. The ball heads at both ends can be locked in place using the large central screw, which holds everything firmly.
Works perfectly with my Insta360 X camera, providing a stable setup. Recommended!

This accessory is essential in many photography and video jobs, allowing us to attach accessories with a standard 1/4 thread to the camera or other mounting points on a tripod, gimbal, camera cage, etc., such as monitors, spotlights, microphones... with the advantage that we can put them in whatever position we want.

Although there are longer ones, I personally prefer these small ones to mount the monitor to the handle or camera cage, since they are enough to place the monitor in the position we want, saving weight and space.

The aluminum construction with orange details is of high quality, the adjustment is quick and easy, maintaining the position firmly.

It includes a clamp to be able to anchor the arm to tripod tubes, study stands or any other edge that the clamp can grip (although from experience, round tubes are much better than table edges, because it makes better contact and requires less pressure).

Right price for a very useful and specialized accessory like this one.

this product is great for action cameras - I tend to record BTS (Behind the Scenes) footage with an Action 5 pro, and this magic arm allows me to attach it to my tripod or to the camera itself. I find this product incredibly high quality; the clamp is very strong, and the arm is flexible. I'd recommend this product.

I bought it to use for a church camera. Provides good solid support and is easy to set up.
