What is this a bong attachment? What does it do exactly? This is not a cloud blower. MF even says that to do it correctly you won't be getting huge clouds or even any visible vapor. When I pack a fresh trench those first 3 hits are very tasty fresh bud like flavor cloudy vapes. then after that it tapers off almost completely by the 4th and remaining draws. that's how it's been for me. I would not recommend this to someone that wants to blow clouds. Me I could give a fuck about clouds as long as I get medicated. I am not exactly familiar with a space case I thought the were good grinders. But your basic 2-3-4 piece grinder with the metal teeth will not get the grind fine enough for the MFLB. My cromium crusher grinds it to perfect joint rolling consistency and what I consider the perfect grind for smoking but not for the LB. Pre grind with your space case and then finishing grind with the MF FG. That's what I do. I just pre grind a bunch into a tightvac/pocketvac which is a nice little odor free container for $5.99. CHeck Amazon for the finishing grinder. They have the lowest price. I got mine for $25 and last I saw they were now only $22. So worth it. Finishing grinder and power adapter are must haves. You can grind with a plastic pill contaoner and a nickle but the FG is sweet.
