The principle of rotating the tripod head is very beautiful. Alls works egg timer moderately mechanically without extra batteries etc. Very good. Unfortunately, it really takes a whopping hour for a Rundumdehung. That makes only sense in still life, otherwise it will be a great highlight and motion wiping washing. In video you also need a new soundtrack in post since the chattering of the drive can be heard. For myself, this is a nice gimmick, but I will certainly use no more than 1-2 times per year and only in deserted areas.
