yes i mean the stereo matrix. i hear the vapecritic don't like to vape anymore. maybe you can buy his old rig from him.
Newvape does not have them anymore. but there is tons of other glass to choose. or just buy roor bubbler, which is basicly just a herborizer clone at 3 times the price. i love the matrix percolators better than showerhead percolators personaly, it just has better stacking smaller bubbles which makes the matrix perc a bit smoother.
In the cheap bubbler/bong topic the D020 and D020-D are popular bubblers.
here is a youtuber doing dab hits with d020-d (i think there is to much water in there):
