11 Inch Adjustable Magic Arm and Super Clamp with 1/4" and 3/8" Screw Holes for Camera Rig, Monitor, Flash Light, Sports Camera Rig

There are lots of these to choose from, so I selected the cheapest I could find. Initially, I was a bit disappointed that the two ball-joints at each end of the arms (for attaching to the clamp, and attaching to the phone holder or camera) weren't tight enough. They seemed to rely on friction and it just wasn't sufficient. But I eventually realised something that nothing on this page and nothing in the box tells you: the single tightening bolt in the middle ALSO tightens to the two ball joints at each end of the arms. Very clever! So, the way to use this is to tighten it up enough that you can get everything exactly how you want it, and then tweak the bolt really tight clockwise and the whole thing becomes solid. The only consideration is the simple threads have no locking pin, so gravity can cause them to unscrew, depending on orientation. For lightweight tasks, though (like holding a phone), this is a really handy device.

It does what it says on the box.Simple to use, it all tightens up nicely when you turn the central knob/wheel.Holds accessories in place.Good value for the money.

Once I realised the central tightening nut tightened all joints it became easy to use. Solid and well engineered. would buy again

For £12 you cant go wrong. The arm is just about 11" in TOTAL length. It comes with a good selection of accessory screws etc. The body of the arm is fairly thin and probably wont withstand a big load, but for small lights, and webcams its great. I've used this to mount a webcam in a streaming rig and its perfect.

Articulating arms (proper name) are great for positioning cameras, phones, monitors and all kinds of things from a solid support. The arm, once tightened, will not give at all. However, that's not the case for the attached items as they're attached by the 1/4 x 20 screw threads at each end. And anything mounted leftward will unscrew due to gravity, simply because screw threads are right-hand. So that's what will let you down, and if you then tighten the screw threads even more, something's going to break. There are more expensive articulating arms that have anti-rotation pins and thumbscrews you can tighten using a hex key as a "tommy bar" but they're three or four times more expensive. I'm giving this three stars for the rigidity of the arm itself, but it loses two stars because the screws will only remain tight if the weight is clockwise, and the lock nut threads stripped.

At this stage ive no idea what this products intended use is because I have used it about 100 different ways and it's been perfect each time

The media could not be loaded. Purchased for my insta 360 and the arms do not connect together so cannot be used as unsafe

They're SO amazingly useful and versatile for so many things! Definitley have some in your kit bag!
