Hey, thought I'd chip in about the liquid pad… I found after some months using the liquid pad it was becoming really rubbish. The pad was restricting the flow of air too much, I think as it started to either gunk up or become compressed. I've been using it since without the liquid pad, still using just small amounts of plant matter — a smallish pinch, just enough to cover the screen in a light way, there is still a lot of the screen showing. Then when I'm using the Plenty I make sure to hold it upright, so the herb doesn't move. Also, don't draw too hard, and don't draw at all if you're opening the chamber (you may not do this, but I have a tendency to, the change in suction causes the herb to fly around the chamber).
