Excellent. Has exceeded expectations. Good quality and clever engineering.

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

Ich nutze diesen Klemmarm um mein Lenovo M10 Tablet am Stativ zu befestigen. So kann ich schnell meine Fotos von der Kamera darauf spielen und sie gleich größer betrachten. Der Klemmarm ist wirklich gut verarbeitet und Stabil. Mitgeliefert werden gleich 2 Ersatz O-Ringe die bei Verschleiß auf den Kugelköpfen ersetzt werden können. Klare Kaufempfehlung von meiner Seite.

Clamps like this one should be in every videographer’s bag. This one is a great quality build with 10 ¼” threaded wells to add just about anything you need to your set. The clamp opens wide and has protective rubber padding on the inside. Everything is machined perfectly. I use these clamps on tripod stands, overhead bars, and tabletops. It has good gripping and stays where I put it without worry. So simple, so easy to use, and so necessary for solutions when filming. Plus, it is very portable and small. Five stars.

This is an absolutely fabulous attachment for attaching 1/4" to 1/4" with easy articulation and adjustment. The double ball joint and the knurled grips for screwing the threads are perfectly robust and well made. K&F products do not disappoint and this product is no different. The O-rings on the ball heads are a fantastic idea and provides a solid and assured grip when locked. Absolutely thrilled with this product and will continue to buy K&F products.

This is my review for the: K&F Concept MS13 Magic Arm with Super Clamp, Super Clamp with Two 360° Ball Heads, 1/4" Thread and 1/4" Screw Compatible with Camera, Phone, GoPro, Tripod.

This Super Clamp is simply amazing!! I love things that are not skimpy on materials but built rugged and built to last. This product exceeds my expectations from every last detail. I love that this comes with two 360* ball heads that offer endless rotation positions and angles!! This will be so much better for recording nature as it will be nice and steady and not shaking or vibrating because I’m trying to hold or angle my phone or GoPro. With this Super Clamp it will do all the work for me. This really is an amazing product and I highly recommend this product! I would give it 10 stars if I could. Thanks so much K&F I love it!

The video goes into much more detail, including a demo of all the features.

However, in a nutshell:

Things I liked:

+ Really solid, weighty construction that feels great. Firm grip on just about any surface or pole you choose to use it with.
+ Loads of additional quarter-inch mounting holes.
+ Included smartphone and Gopro holders.
+ £29 seems pretty reasonable, although it was around £25 when I first ordered it.
+ Excellent freedom of movement in the mounting arm. Loads of control over full positioning.

Things I didn't like:

- Didn't like how the mounting arm came away just as I was saying it wouldn't come away on the video. But that's my problem, not yours.

Do I recommend it?

Yes, absolutely. Good quality clamp and reasonable price.

Versatile and with excellent functionality. It allows the use of the clamp and arm independently with the possibility of screwing on multiple accessories and devices. Perhaps little contact surface to attach to glass such as the car window. Good
quality materials.
