I bought this Knockbox because of the size and attractive design, the previous model had unfortunately given up the ghost. The material quality / -anmutung is impeccable, the wall thickness of the container is very neat. Unfortunately, the daily use leaves a little to be desired. On the one hand I could also watch the wobbling effect, because the foam rubber on the ground has a significantly smaller diameter as the vessel (probably due to the optics). On the other hand, the dismantling of the crossbar quite expensive (but unavoidable if one wants rinse the part). Since there are better designs.
Addendum: I have now enlarged the two holes for the cross bar with a minimal Countersink. Now can the threaded rod pull out relatively easily. Always is not yet perfect but a significant improvement.
