MHW-3Bomber F74 導航員用風箱

Ok. With the right technique it works. Wish it was rubber instead of filament but it's fine. It works once you get a routine down.

This bellows fits my MHW-3Bomber F74 grinder bean inlet funnel and corresponding cap precisely, and works well for its intended purpose. I have not had it long enough to gauge how it will last and perform over the long run, but do not presently anticipate any problems in that regard. Shipped quickly and was carefully packed. Good communication from the seller.

Bought it with some initial doubts as there were not much information or reviews, but went with it and it fits perfectly. I use it with RDT and grind retention is almost zero. Love it

This is an ideal, essential addition that makes a good grinder great.
