Nice review. Just a couple of points, If you herb is shifting, you aren`t using enough product, try using your liquid pad on a less than full load to stop movement. See above. The instruction book and earlier posts describe how to stick your cleaning brush into one of the screw holes at the base to be able to stand upright, you will also notice the Plenty has rubber feet on one side for sitting it on it`s side. You have chosen a big hitter for your first vape, enjoy getting to know it.
