A test with the Cullmann Cruiser has no significant improvement over the freehand films shown (small DSLR, 1kg with lens).
As a comparison, I have a Cullmann Nanomax (retracted legs, 3-way head angled 90 degrees) as a stabilizer 220 attempts (the three legs so against the torso put) and achieved a much better result. For this would probably also the Nanomax 200 sufficient that also has a better pack size.
Basically I came to the conclusion that a 1-point stabilization, neither vertical nor horizontal, but only forward / backward stabilized, no benefits.
So apart from the fact that you can not really cruising with the Cruiser, the tripod is small, light and well finished. Specifically, the clutch is extremely solid, unfortunately the plate has approximately 1 to 2 mm play forward / backward, and is not compatible with the Nanomax 220. However, this should not be relevant in practice.
As somewhat limited Tischstativ it safe enough from all times.
