The “Magic Arm with Super Clamp” is made almost entirely of metal/aluminum and therefore makes a good impression. The clip can be opened quite wide and closed firmly. The “magic arm” consists of two ball joints — this allows you to make almost any adjustment and you are really super flexible. The lock holds well, but it's a bit to the detriment of the rubbers. For this reason, there are certainly two spare rubbers included. The upper attachment has a stand thread, which can be locked by turning.
I have the following complaints: I think the tightening levers are longer on one side in order to be able to exert more force. Clever actually — but at very tight angles, this prevents tightening because the lever then hits the arm and cannot be rotated. The tightening of the tripod thread could also have been easier: everything is quite round and you slip off very easily. In addition, it is relatively small, which makes it difficult to exert enough force. There are small recesses, but they are of no use — if they were continuous holes, you could use the enclosed Allen bowl, for example, to tighten.
Last but not least, the clamp could have been fitted with a slightly larger rubber surface to maximize grip.
But since the manufacturer's service is really good, it remains 5 stars despite the minor review!
