One day I accidentally smashed the screen all the way to the bottom of the box, twice, and my box is totally fine still... I'm sure I got lucky but IMO it's pretty flexible, and stronger than it seems. I haven't used the box for many concentrates.. But since you can access the mess to wipe it up, I would think it would have less of a fouling issue than a MFLB.. Maybe the reason for the black (paint? dye?) coating is to keep the oil from absorbing into the wood?? Have you been wiping it down, and still having odor issues? I would just use a Q-tip. I don't know what else you could do. Considering how the screen can get glowing red, you can just do a burn off and carefully brush it off.. I haven't tried, but I would assume that Bubble is a no-no.. And it just sounds ridiculous to try and load Keif in something that tiny that can glow red hot.. I don't really see Shatters being much of an issue, regarding the screen. I personally enjoyed the Kava, but I would prefer to drink some. I totally forgot this thing was called the Maud-Dib.. that's probably gonna take me a little bit to get used to.
