It can't get much better for a mount of this type. First off, all of it is aluminum. Even the 1/4-20 knobs. And I really like that the clamping knob is asymmetrical and a bit longer than what I normally see. But the best feature is that the heads are knurled with a texture so that they hold much more solidly than other ones I own. There is no slipping at all. The only "weak" point on this is that there are no locating pins. So you just have to be aware of the weight and angle of what you are mounting. With any mount like this you want to watch that the weight and angle of the load does not cause it to twist loose. You can really bear down on the knobs, but eventually this will weaken or smash the rubber pads.Overall though, this was just right for attaching my Insta360 X5 to my Lumix S5IIX cage. Now I can get POV footage of my next photo walk.Overall this is just what i expected from the quality of K&F. I really like what they are making, the engineering is thoughtful and the build quality is great. The finish on this part is a really nice matte black and deep orange. Plus K&F never has a surprisingly high price point. I think this part especially is an extremely good value.

The K&F Concept Dual Ball Heads Magic Arm is a compact and versatile mounting tool that quickly became a staple in my gear kit. Made from durable aluminum alloy, this mini articulating arm feels solid in hand yet remains lightweight enough for portability.Equipped with 1/4"-20 threaded screws on both ends, it easily attaches to a wide range of equipment - DSLRs, action cams, monitors, LED lights, flashes, cages, and microphones. It’s a flexible solution for photographers and videographers who need fast, adjustable support for accessories.The dual 360° swivel ball heads provide exceptional maneuverability, allowing for nearly any positioning angle. You can rotate and tilt freely, making it simple to fine-tune your framing or lighting setup. Whether you're working on a tripod, camera rig, or lighting stand, this arm adapts smoothly to different mounting needs.Additionally, the wing-style central knob rotates 180° inside recessed grooves, locking both ball heads firmly in place once adjusted. It’s a smart, low-profile design that gives you maximum stability without adding bulk.This mini magic arm might be small in size, but it delivers big on functionality. Whether in a studio or on the go, it’s a dependable and precise mounting accessory that adds flexibility to any shooting setup.

I’m very pleased with this small compact double ball head. It’s solidly built and functions really well. The mechanism locks both balls simultaneously and the lock is very, firm, leaving both bowls locked firmly in place. The balls, each have 1/4 inch screws attached which makes them very versatile and able to connect to a wide variety of objects.

Straight metal, good quality, simply works perfectly, as good as it gets

Got it to use my Insta360 camera as a webcam, by the time I figured out a decent mount I needed a device like this to get it situated correctly and this mount arm worked perfectly. I can see tons of uses for this too. As a test I mounted the Fuji XT3 on this arm and it held up fine, this was a stationary mount though not a moving vehicle or anything like that. I also only had a small 27mm lens attached.I like it and would go with this one again if I needed to.

Right out of the box, I was impressed with the quality. It feels solid and well built. When you tighten it down, it does not move. There is zero play, which is rare for a mount like this. Wherever you position it, it stays put.I like the orange lock knob because it is easy to see and find quickly. It feels comfortable to use and does not require a lot of force to lock it down securely.I am using it to hold and articulate my iPhone in the studio, which makes setting up shots much faster. I would not hang my DSLR on it, but it feels like it could take on more weight than I am willing to test. I am sure I will find many more uses for this piece of equipment. I also like that it is made entirely of metal, which adds to its durability.

I’ve seen many ball clamp, accessories for mounting, various photographic accessories, and other devices. This is hands-down, the most well built professional level ball clamp that I have seen today. With the exception of the 1/4-20 tripod mount tightening discs, the rest of it is all made from machined aluminum components. It is very small and compact, but also strong as an ox. Once you set it and tighten the thumb knob, it will take a lot of force to get it to move out of position. It’s also very light, so for those of you who end up carrying an abundance of gear, this won’t impact your load much

The balls have texture on them so the arm halves really grip onto them when you crank it down. The thumb knob cannot be removed fully, and thus the two ends also do not detach, preventing you from losing any pieces when transporting it. The thumb knob also has a plastic washer that allows you to vary the tension to a degree for easier repositioning. There are two 1/4 threaded holes on one of the two arms so you can get creative with mounting things, or just use them to store spare screws!

This K&F Concept Magic Arm is one of those tools that may look small, but plays an absolutely essential role on set — whether you’re working in photography or video production. When you need to mount lights, monitors, microphones, or any kind of accessory exactly where you want it, this is the kind of hardware that quietly saves the day.I’ve used many products from K&F Concept over the years, and this one continues the trend: well-made, solid, and thoughtfully designed. The aluminum alloy build keeps it lightweight but extremely strong, and the locking system — with a single tension knob — lets you adjust both ball heads at once. That means you can operate it one-handed, which is exactly what you need when the other hand is holding your camera.Whether you’re attaching a small LED light, mounting a monitor to a rig, or placing a microphone in a precise spot — this arm gives you full 360° flexibility with no wobble, no slip, and no second-guessing.In my own setup, I’ve used this Magic Arm to mount a compact light, an action camera, an on-camera monitor, and even an iPhone — all attached via cold shoe. It handles each item with confidence, even when things get dynamic. And being able to do all that with one hand free is a huge advantage when working solo.The 1/4”-20 screw mount makes it universally compatible, and once locked in, it stays exactly where you put it. No drift, no looseness, no readjustments.Bottom line:This is one of those accessories you don’t realize you need until you use it — and then you wonder how you ever worked without it. Simple, reliable, built to last, and a perfect example of K&F Concept’s practical design philosophy.

This magic arm from K&F Concept has a distinctive style that sets it apart from the competition. It’s a design that emphasizes how it looks as much as how it functions. Indeed, to my eye, this magic arm has a sleek stance, with fast, aerodynamic lines. If this magic arm was a car, it would be a Formula 1 racer.And yet there’s more to this magic arm than just good looks. It has a solid build, skillfully crafted from quality aluminum alloy. That makes for a mounting extension that’s lightweight, yet structurally sound.Like virtually all magic arms, the two ball heads are free to rotate, allowing for a range of positioning options. Each ball head is tipped with a standard 1/4”-20 threaded screw. Onto which is threaded a silicone padded platform. A typical set-up would have one end of the magic arm attached to a super clamp, and the other available to hold a compatible device. For example, an LED fill light. Once the magic arm has been loaded and set, there’s a large wing nut that pulls the two socket plates together, locking the ball heads into position. I’ve used this K&F magic arm in several different set-ups, and observed no tendency of the ball heads to drift out of position once locked. Of course, stability of the ball head is critical for any application.And yet there’s more to offer from the K&F Concept magic arm than just a “typical” set-up. Thanks to a set of 1/4”-20 threaded mounting holes that have been cut into the rear socket plate (i.e. opposite the wing nut). Those holes can be used to attach the magic arm to a super clamp, or any other style of mount (via an extension), freeing up both ball heads. Alternatively, the holes can be used to mount another set of compatible devices. Bottom line, the K&F Concept magic arm is a highly versatile accessory, with the only limitation being the users imagination.
