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

This K&F Concept magic arm with super clamp is a very versatile design that enables use for a multitude of situations. There are no instructions included but none are needed if you are familiar with these types of clamps.

The clamp opens super wide, up to 60mm (2.36") with rubber tipped grabbers so this can be used on the edge of a desk with no fear of scratching. The clamp arms are curved so they can be wrapped around bike handles, poles, and tree trunks. There are many holes on the clamp for attaching the magic arm. You can choose one of the 4 holes on the sides of the two arms or the two holes that sit at the top (where the arms come together). If you have other arms that you want to mount to the clamp note that it has 6-1/4" threaded holes.

The magic arm has 360-degree rotating ball heads at each end that give you maximum flexibility in choosing the angles of the arm. You have to loosen the orange handle to rotate both heads and then tighten down the orange handle when you have both ends in position.

The ball head on one side has a unique feature I haven't seen in other clamps: a very nice locking tripod screw that makes it a bit easier to get your device mounted. And this kit includes two mounting options:
1) GoPro mount - standard one with screw included
2) phone clamping mount - you flip up the little arms that grab your phone and just pull to open it up; there is also a weird little flipper on the back that lets it angle away from the tripod screw, but I won't be using that feature.

You also get a small allen wrench with two O-rings. The allen wrench lets you get a super tight fit on arm when it is placed into the two holes at the top of the clamp. Put the magic arm into the hole and then tighten the small screw. I believe the O-rings are to be used to replace the rubber ridge ones on the rotating ball heads when they get worn down.

Max pay load for the clamp and magic arm is 5 kg (11 lbs.). This is a nicely designed magic arm and clamp at a super good price and I highly recommend it.

This clamp has become the newest item in my bag for road trips. It has eliminated the need for one stand I typically use for my iPad when I'm tethering. I just clamp it to a C-stand or tabletop and forget about it until I'm done. It holds strong and doesn't droop over time like some others out there. I've also used this to hold a 300pro strobe in a tree or two and had no worries. My only complaint is the phone clamp. I don't understand why a company would make something so well-designed (the clamp) but include something so inferior (the phone clamp) with it. The phone clamp lacks the heft and the solid feel of the main clamp. Honestly, the phone clamp just sits in my drawer. The clamp should have been made of the same material as the main clamp. This would have made the set top-notch.

I have purchased a number of arms and clamps that have been very disappointing since they could not hold that much weight at all. This setup has not disappointed me. It can be quite stable with some substantial weight on it! The other thing that I really like about this is that the clamp can be mounted in a variety of positions using a selection of holes all over the clamp.
Adjusting it is as simple as could be, with the screw turning smoothly and not needing to be turned with great strain to keep position. It is a pleasure to use this and know that what I am holding will be steady and reliable. For 25 dollars, this is well-priced and valuable!

I use this to mount a webcam to one of my 3d printers to monitor the prints. With this system you can pretty much mount it to any part of the frame or enclosure and it works perfectly

I've used this on a smaller mirrorless camera for several days now, and it works quite well. It holds securely and is almost infinitely adjustable. I haven't used it on anything as large as a DSLR yet, but I'm confident that it will work fine for that. There is no slippage or backpay when the locks are tightened down. Very handy little item for your field kit.

This is much higher quality than I thought it would be. Right away, you can feel a bit of weight to the box and in hand it's clearly quality materials. The controls are pretty simple and straightforward and it has options to mount a phone or GoPro. I have a 360 degree camera which this will be ideal for. The only thing I didn't like is that there are two joints which tighten and loosen on the same knob which I imagine can get complicated when trying to adjust to a perfect angle on that end. Otherwise, this is great and will get a lot of use in my camera bag.

This is a very cool attachment that allows me to extend the attachments and equipment I have on my tripod. The clamp has very sturdy adjustments with a range of motion that gives angles in any directions. I can add more lighting, a mic, and a secondary mobile device to capture other video angles.

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!

This Magic Arm/Super Clamp combo from K&F Concept is very well made and sturdy. It's compact and easy to keep in a bag. Straightforward enough to use. The knobs tighten securely and can release with just a bit of effort.

The phone mount and GoPro mount are nice extras and both work to hold their respective devices. The phone mount is a rather compact design itself, very cool. Two O rings included, I guess those much be a weak point that need replacing? So far I've not used it enough to have it be relevant.

While I could separate the magic arm from the super clamp it seems a bit more involved and not sure it'd be practical for me in use.
