진동 디스트리뷰터/vibration-distributor
A vibration distributor (e.g. Nurri) settles the coffee bed by vibrating the portafilter. It distributes somewhat but does not break up clumps well, and causes 'sandbagging' — fines settling to the bottom — which slows flow compared with needle distribution. It reads more as a fun gadget.
