The “Magic Arm with Super Clamp” is made almost entirely of metal/aluminum and therefore makes a good impression. The clip can be opened quite wide and closed firmly. The “magic arm” consists of two ball joints — this allows you to make almost any adjustment and you are really super flexible. The lock holds well, but it's a bit to the detriment of the rubbers. For this reason, there are certainly two spare rubbers included. The upper attachment has a stand thread, which can be locked by turning.
I have the following complaints: I think the tightening levers are longer on one side in order to be able to exert more force. Clever actually — but at very tight angles, this prevents tightening because the lever then hits the arm and cannot be rotated. The tightening of the tripod thread could also have been easier: everything is quite round and you slip off very easily. In addition, it is relatively small, which makes it difficult to exert enough force. There are small recesses, but they are of no use — if they were continuous holes, you could use the enclosed Allen bowl, for example, to tighten.
Last but not least, the clamp could have been fitted with a slightly larger rubber surface to maximize grip.
But since the manufacturer's service is really good, it remains 5 stars despite the minor review!

Good arm for cameras and phones, all made of metal except the included mobile phone holder. Tightly tightened, a support is fixed at any angle. Recommended for quality/price.

Excellent support, prepared for any situation and very useful for the next Simracing lives

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.

This little unit is the perfect travel companion to have. Its compact size means you can keep it in your camera bag, glove box of your car etc. the clamp opens pretty wide so you have a a range of items to clamp to when requiring a still camera. Perfect for that long exposure shot. It’s also great for holding your phone on day a bedside cabinet or similar if you want to watch videos on your phone. It also comes with a bracket for holding action cameras so you have the capability of clamping to your bike handlebar etc. Great value.

Good functional product. Compared to similarly priced (although bit smaller) Smallrig arm and clamp:
- The rotatable screw mechanism with ARRI pins in MS13 is better for most use cases than the screw and rubber ring on Smallrig. The pins retract and there is rubber for anti rotation for non-ARRI use as well.
- Magic arm ball locking is more reliable. Especially in positions where the magic arm ball rubbers engage, they make the locking very rigid and rotation resistant. On the other hand they make turning stickier and finding the correct position harder
- Magic arm balls have more freedom of movement, which is also why the position where rubbers don't engage can mostly be avoided
- Clamp feels bit more solid and has less play than Smallrig clamp, but doesn't open as wide and jaws have less rubber padding. When locking on a pipe or tripod leg, this clamp will lock with bare metal as the rubber pad doesn't reach far enough. Fixable with bit of glue and rubber, but a weird oversight.

Either one will do what they're supposed to. K&F MS13 one has significantly better magic arm, with better locking and movement range. Smallrig clamp doesn't require glue + rubber mod, opens wider and has one extra female 3/8” ARRI interface, so despite the slightly less robust construction I would rate it bit higher due the added versatility.

Absolutely love this clamp! Setup is super easy, the grip is strong, and it’s perfect for my GoPro and phone. Reliable for travel or home—highly recommend for creators!

I was looking for something that I could mount a DJI Osmo Pocket 3 in my car. No suction cup style mount would work because of the shape of the windscreen - if the mount was in arms reach it would obstruct the field of vision and for it not to block vision, it would be too far away to safety turn on while driving.

I then came across the Magic Arm from K&F. I had a similar mount from another well-known brand, but that mount was much heavier and with a long arm, which caused the camera to shake a lot and therefore none of the footage was usable.

The Magic Arm from K&F is small, lightweight and most importantly - holds the camera very securely. I was even brave enough to mount it to my rear view mirror.

Pros: lightweight, stable and secure hold, good workmanship and well made, good value for money, modern black and orange color scheme.

Cons: in my opinion, I don’t think it’s necessary to include attachments for other devices (phone, GoPro); the standard 1/4” screw is enough - the other attachments could be bought separately as required.

ENCHANTED. The materials are super resistant, I was afraid that it would not hold up well to the weight of the monitor (Ninja Flame Atoms) but it has exceeded my expectations. I recommend it 100%.
Even the mobile accessory, which is the only thing made of plastic, looks good quality.
This brand does not fail.

I’m a huge fan of K&F products, especially their lens filters (I have five filters that stay permanently on top of my lens). I decided to try this clamp to see how it would perform for creative shots in the future. The product feels solid and not flimsy, as the entire clamp is made out of aluminum. It clamps well onto railings, edges, and other areas where you’d want to place it.

However, when using my iPhone 13 Pro Max, it does feel a bit unstable since the weight causes the clamp to shift slightly. Another issue I noticed is that when using the leaning feature during horizontal shots with the phone clamp attachment, it sometimes rotates on its own, as if it cannot handle the weight.

That said, I found a nice alternative use for it as a makeshift camera strap attachment to my helmet, which worked surprisingly well. The only drawback is that if you’re moving around a lot, the locking mechanism can loosen itself, which may cause your phone to fall off. This isn’t a major issue, though, since you’d typically use this clamp in stable environments.

Overall, for its price, I’d give it a solid 4/5. Just be aware that if you’re using a larger/heavier phone like the iPhone Pro Max, you may run into challenges that you wouldn’t face with a smaller, lighter device.

Edited; KnF reached out and gave me a refund for the product. At the same time I've given the clamp to my friend who has been using it with his GoPro and have zero issues that I've mentioned above. Incredible customer service and would definitely buy from this company again in the future. 5/5 Stars.
