This arm is a very practical accessory for mounting anything form a camera to lights/microphones or even as a camera-handle itself. There is one negative to it, though. The mechanism on my copy sometimes when tightening made a cracking noise, and for some time it wouldn't tighten or loosen up as much as it should, which went away after some time. If I need another one, I will get the manfrotto friction arm, which is more expensive, but I can tighten it with a screw mechanism, and not a springy one like on this.
These arms are very well built and have a clever mechanism that allows you to position whatever is on the end of it easily with one hand, whilst leaving the other free to lock the arm. The arm locks firm and feels like it would handle a good weight before it moved. One of mine became stuck shortly after purchase. A search revealed that this is a common fault. I had to open up the centre cam and reposition 3 ball bearings that had jumped out of place. Now working A-ok again. I use mine for positioning radio microphone aerials and for this purpose they are perfect.
