I'm really excited about this mount. The materials used and the quality of workmanship are of a very high level. All parts are made of anodized aluminum and are neatly finished. There is an arm with a joint in the middle and a ball bearing at each end. The joint can be secured with a wing screw, which also fixes the ball bearings in position. You can therefore fix or release the bracket with a single adjustment screw, which I find quite practical for everyday use. See also my attached video.
In addition to the arm, a clamp/screw clamp is also supplied, which can be opened and closed with a screw. Rubber is attached to the inner sides of the clamp so that damage to both the clamp and the object to which it is to be attached is avoided.
In addition, a mobile phone clip is also included, which I like to misuse from time to time and has already been attached to other objects such as masonry. That also works, despite the weight load from the arm and microphone. Like the clamp, the mobile phone clip is also lined with rubber material on the inside to prevent damage due to contact.
The arm can be screwed onto a clamp or mobile phone clip using a 1/4 inch thread. Or you screw it to any other device that has a 1/4 inch thread. The clamp also has a 3/8 inch thread, but I did not use it. In any case, the articulated arm does not have a 3/8 inch screw device.
I have used the mount with both a Zoom Field Recorder (microphone) and a Xiaomi Action Cam (camera) so far. When it comes to static camera or audio recordings (field recording), the Magic Arm impresses across the board.
I therefore absolutely recommend it!
