Basically, it is a very stable Neiger. If you tighten it one need not worry about that, he slips. But there are two points that bothered me. First, the axis has some play. The symptom is that the Neiger in firmly drawn state something wobbles back and forth. As long as you use a lens with an overweight to the front, that's no problem. But if you balanced the weight, you have to fight with an unpleasant wobbling. The second point is more a matter of taste. I'm not a fan of the mechanics, with the release plate is secured. It requires for my taste too much force to push the red bolt in. And the mechanism is compatible only to itself. If you use other Arca plates do not have the right over the recess. This means that you constantly have to fight with the backup without it would benefit. Therefore, I sold it back.
