[2] I bought several of these mounts already, but let me start by stating that I did NOT buy them for their intended purpose (which is for mounting small cameras like a personal handheld or a GoPro to a stationary base, or perhaps even lighter professional cameras)... Instead my use of them (misuse of them) was to attach arrow quivers to the side of high-powered hunting crossbows (I wanted to be able to infinitely customize the position of the quiver assemblies). And for my purpose this mount ALMOST worked beautifully. It easily supports the added weight (more than that of any of my cameras) and it seamed very solid and appeared to hold up to the much greater leverage presented by a 22 inch long arrow package against its tiny 1/4 inch balls (which made for a rather extreme fulcrum point), but field testing revealed that it would slip slightly from recoil-shock when actually shooting (which in my case created a potentially hazardous condition that could get someone hurt). And so in the end I upgraded the bows much larger 1 inch steel and rubber ball motorcycle camera mounts intended to take road vibration and shock of potholes (and this worked perfectly)... Anyhow, that is not what THIS tiny 1/4 inch all-metal mount was ever intended for to begin with. But I can tell you that my misuse presented real-world test conditions which were way-way more extreme than you should ever encounter when using it for its true purpose. So I'd expect it to work out absolutely great as an actual static camera mount. It really is a solid design; very compact, all metal, precision machined parts, even the turn knobs are metal, so you can really torque this thing down very tightly without it failing; there is no plastic in any of the design. It is very clearly well worth the money. And I will definitely still use the 2 I have to set up stationary cameras in the field. In fact, they are so nice that I will likely buy more to use with all of my trail-cams.

[1/4"-20 Male ] I use it to hold camera remotes exactly where I need them. A pin in the 1/4 thread holes allowed me to add a Varizoom rocker on the same assembly. This is a versatile problem-solving widget.

[1/4"-20 Male ] Really, really tiny, which is great because I'm just throwing it in my camera bag as an extra monitor mount. Seems solidly built!

[1/4"-20 Male ] I purchased a few of these to make a custom mount for my car to hold the iPhone I use for navigation away from the dashboard to keep my phone from overheating in the summer. Works perfectly. Stays tight and exactly where I want it. They also seem to be made well.

[0.18 lb] Looked at a bunch of different arms and landing on this one. My old Hollyland kit came with a similar arm and I was looking for one just like it. This works and it is sturdy. I am using it to mount my teradek transmitter to my camera.

[Aluminum] very well built and useful and the price is amazing

[1/4"-20 Male ] The magic arm is pretty easy to use, the whole thing loosens and tightens with a single clamp which is really nice.

[0.18 lb] Beefy enough for what I needed it for. Knob has a good bite to tighten it down.

[Aluminum] I've got two of these and plan on buying more soon. They're nice and small but still strong enough to hold my Ninja V with no issues.

[2] Very well built magic arm. Wish they have a 3/8 to 1/4-20 because very few things actually have a 1/4-20 mount with locking pins.
