K&F Concept Ms13 Multi-Functional Super Clamp with Ballhead Magic Arm

Excellent product, recommended, fulfills what is promised.

I use these clamps on my drum kit and if I'm honest, they can handle a serious beating. I don't need to readjust the magic arm, ever... like **ever**. That alone is a god-send. Thanks K&F!

I bought this arm to support an overhead projector and it works great. Very easy to articulate and supports weight easily. Its design allows it to be installed almost anywhere, which is what I was looking for.

K&F Concept Magic Arm with Super Clamp - very light, good quality, works perfectly with light cameras.

I needed one to use with my insta 360 x3 and it works well, until you use an extendable stick, the ball bearings slightly move from the road vibrations while cycling.

The grip is good but in my opinion it needs a bit more rubber inside the clamp to prevent scratching my handlebar.

It is easy to use and it fits well, made of aviation metal.

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.

Sometimes, there are peculiar scenarios that require you to adapt. This clamp and magic arm can help you adapt to some situations.

Anything that has a 1/4" screw hole can be mounted to this mounting system, just be wary of the weight limits of course.

I mounted a Hobolite Micro LED light and attached the clamp to a floor lamp. The lamp has a very skinny pole, and despite that obstacle, the clamp was still able to latch on and keep my LED light at the position I wanted it to be in.

If you need to reach further lengths, you can purchase a longer magic arm and detach the magic arm that comes with this kit. I've seen some clamps with a built-in, non-removable magic arm, which is a no-go in my books. Thank goodness this one has a removable magic arm.

With all of that said...Overall a solid option as far as clamps and magic arms go. Recommended.

This is more compact than I was expecting, but that's a good thing. At just under 8 ounces, this will be a no-brainer to toss in my camera pack. I've had great experiences with K&F Concept products so far, and this doesn't seem like it will disappoint. It feels very solid, both in hand and in use—while they are rating it at 5 Kg (about 11 pounds) I don't think I'd put a 6 or 7 pound camera/lens combo (I'm mainly shooting medium format at this time) hanging off of it—but would absolutely position most APS or smaller full frame bodies and lenses with it; and most flash systems, which is where I think this will really shine. I will hike with a tripod, but not with light stands, etc.—and I can see this as very useful in holding a fill flash or wind blocking panel, say.

The machining and finish on everything is quite nice.

Why not 5 stars?

1. There is no instruction sheet, of any kind. Heck, I'd be happy with a QR code that takes you to the correct page on their site. Not that the direct usage of the clamp and arm really needs instructions, but I still end up with questions.

2. The "magic Arm" has two ball joints on it, that seem to rely on O rings. The package included 2 extra O rings, and a small hex key, so I can see how one would use the hex key to open up the two ball sections and replace the O ring—but... What is the life span of the O ring? (I know I can order more from McMasters, or even probably pick them up at a well stocked hardware store, but still, the idea of the grip depending on a piece of rubber that is replaceable doesn't sit right. Although, to be fair, it's possible that the gripping only pinches the rubber, which maybe acts as a friction helper before you tighten down everything?)

3. It's the old compactness versus usability decision, but I think both knobs could be a bit larger. Getting the clamp to stay put on a vertical 2 x 4 would be easier if I could get an additional finger on the clamp.

4. I'd like the 1/4 inch screw plate end to be a bit larger—again, larger is more weight and not as compact, but adding an extra 1/2 inch to each direction of the square base would give you a more secure grip (unless what you are mounting on it has holes placed exactly correct to align with the spring loaded pins on the plate).

The two added accessories—an ultra compact phone holder and a Go-Pro holder, are sort of un-explained. (see #1 above) The phone holder took a bit to figure out, but is clever, and small enough to also throw in the pack. I don't have a Go-Pro, so can't comment on that part.

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 picked up the K&F Concept MS13 (named after the infamous cartel gang? interesting) to be used with various camera and lighting gear.

In the box, you receive the magic arm, a phone holder, 2x replacement O rings, and an Allen Wrench.

The articulation of the arm and positioning is fantastic along with the ability to attach it to dang near anything - with several exceptions - this is where we find the disappointments. On either side of the clamp, you'll find two rubber pads that allow the clamp to hold onto whatever you place it onto. However, due to the fact the rubber is only on the inside of the clamps, which prevents them from attaching to extremely hard surfaces that aren't extra wide.

What I'd change on these clamps is to have rubber that wraps around the outside of the clamp, this would enable you to clamp onto harder surfaces that aren't super wide.

Overall, it's a great clamp with the downside being not enough rubber for clamping onto harder surfaces that aren't ultra-wide.

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.
