Dust does get all over outside of tumbler bowl, but that is what compressed air is for....
I used to run the tumbler with the smaller opening and didn't need the lid. The vertical walls on this unit spill too much. I did prefer just letting the dust purge out and sweeping it up. But overall this tumbler is bigger and better, and the little hole has kept me from losing the lid nut for sure.
