This magic arm with clamp from K&F Concept has been super useful for me when recording. It is very solid, the 360° ball joints allow you to adjust any angle precisely and it is securely fixed to tripods, bars or desks. I have used it with camera, phone and GoPro without problem. The closure system is soft yet secure, and the materials feel premium. An essential tool if you record in different scenarios!

Previously had another brand and it was built great but seemed to get loose often. Tried this out and the quality is amazing, well built and does not come lose even when using on my bike handle bars and jumping.

Excellent product, recommended, fulfills what was promised

This K&F MS13 Magic Arm with Super Clamp is a pro level quality clamp with phone holder and 1/4” screw mounts. It is awesome build quality. The jaw of the clamp is extra wide so it can be clamped, securely, in so many places (counter tops and table tops, handlebars, skateboards, fence post, small tree branch, etc., etc.). I haven’t tried it on a moving object yet, but I plan on using it on one of my next motorcycle trips.

Next to the awesome clamp, the next great features are the two 360° ball heads. These allow the mount to be titled, angled and adjusted to virtually any angle. They are great. This phone is so versatile.

Awsome "Gift Quality" Packaging (See photos below) Definitely Recommend.

I was looking for a clamp to use on my tripod when taking pictures and found this.

This is probably the nicest clamp i have. Its beautifully machined and has no sharp endges. It has a well thought out design that allows for many uses.

The clamp has about a 50mm opening and it take about 4.5 rotations from fully closed to fully open. The lip of the jaw to the adjustment screw is 40mm, so that is the deepest it could clamp on to something. The jaws have 1/4" threads that go through the clamp jaws and 2 on the back, so you can put the arm on 10 different positions on the clamp. The large ergonomic tightening screws are rounded and comfortable.The clamp its self weigh 125.9 grams

The arm is 105mm long not including the threads. It has a two ball joints that tighten on a single screw. The precision allows to make fine adjustments and tightening is easy. The o-rings are there to assist with the fine tuning and it has a very smooth action. The arm weighs 95.1 grams

Over all i am impressed with this. It feels like a well made quality clamp. Also, for the price it is fantastic.

This clamp isn't great flat surfaces, it's made to grab onto poles.

Today I'm reviewing this multi-function super clamp mount by K&F concept,

We'll do a quick unboxing. On the inside of the box, we have a small Allen wrench and two rubber O-rings in a baggie. I see a GoPro mount and a cell phone mount/clamp, and the super clamp itself.
This feels lightweight and I like the orange color that K&F concept has chosen to use. I'm not sure I'm a fan of the rubber gaskets on the balls. I'm not sure if this will make for a stronger connection or weaker connection, only time will tell. I do like how it is spring loaded. The end of the magic arm is 1/4"-twenty and can be moved to one of several holes on the super clamp if one works better for you.
Compared to my other clamps I like how this clamp stays the width you set so no accidental pinching should happen. As you can see this clamp is similar in size to one my favorites but has a longer reach and in my mind this thumb screw is a game changer.
After using clamp for a bit, I prefer the reach of this clamp which allows me to get further away from the pole this is mounted to. I will say, like a lot of these clamps, they struggle to get a good grip on flat surfaces. I would only recommend using these to mount on a pole or rounded surface. If I had to say something negative, it may be that there are only 1/4-twenty holes, most of my other clamps also have 3/8" holes.
For the light I'm mounting this had no problems at full stretch, I shook the pole and no movement at all. So, plenty of grip and these gaskets are holding up so far.
In my opinion, at the time of this review this clamp is about $25. At that price this is a steal in my opinion, the list price is $30, and at that price I still feel it is a fair value. I would recommend this as long as you just need the quarter-twenty mount. This thumb screw is the best in my mind, it's so much better than having to twist the whole mount or the light that I'm mounting.
I'm going to rate this five out of five stars.

Pros
- Good reach
- 1/4" thumb screw works great for keeping position while tightening
- Great grip on poles and rounded surfaces
- Reasonably lightweight at 8 ounces with clamp and magic arm.

Cons
- Not the best grip on flat surfaces
- Rubber gasket longevity is a concern on balls of magic arm
- No 3/8" holes

Allows to clamp on a lot of surfaces
Strong enough to hold a dslr but has a bit of movement with the shutter
Quick setup
Usable at any angle
Comes with good accessories
Very practical and can be a really light and easy to carry alternative to a tripod

As soon as you open the box you know this is a quality product. It feels substantial without being heavy. It clamps perfectly and holds the camera at any angle to suit the application. It comes with spare O rings & very small allen key. The 6 holes in the main clamp are each threaded allowing additional equipment such as mics & mini lights to be attached at the same time as a camera. The two primary locating holes on the main clamp each have a little grub screw. Make sure the grub screw is tightened using the supplied allen key, to prevent the ball which the camera arm clamps to, from twisting when in use.
I clamped my Insta 360 camera to the sun visor for a run up Brooklands Museum Test Hill & although the visor shook around the clamp & the camera were rock solid. (you don't see the whole of the clamp because the Insta 360 software hides it)
A great product from K&F Concept

This Multi‑Function Super Clamp MS13 has proven to be an extremely reliable accessory that is perfectly suited to advanced photo/video use.

Manufacturing quality
The clamp is made of machined aluminum, with a clean finish and a precise thread. The clamp offers a high clamping force, allowing a secure grip on tubes, trays, bars, tripods or flat surfaces. No mechanical game, no feeling of fragility.

Stability and load capacity
Tested with:

Sony A6700 + Tamron 28-200

DJI Action 5 Pro

The articulated arm easily supports a hybrid + zoom setup. Once locked, no drift, even after several minutes or in the presence of slight vibrations. The ball joints offer a wide amplitude while maintaining exemplary rigidity, which allows precise and repeatable framing.

Versatile use
This clamp opens up possibilities that are impossible with a traditional tripod:

fixing on a railing (or tree branch in my case) for stable shots

installing an action cam from a low angle

bracket for light, microphone or monitor creative

angles in vlog or product shooting

Compact and light, it immediately found its place in my camera bag. It is typically the accessory that troubleshoots, optimizes a setup or unlocks a frame.

This is a very handy gadget when you don't have a tripod or when you need to attach your camera to some specific angle or object. Bought this for use with a camera, but found the included phone attachment very handy as it is very sturdy and holds your phone well. Also, as you can see in the photo it holds my camera even with the big and heavy lenses like the Sigma 18-35mm. Only make sure to clamp it tightly as it does tend to move horizontally easily.

Overall, highly recommended as the material feels premium and heavy duty, better than imagined for the price.
