Awesome for dab rigs

I use this piece on my Grav large upright bubbler which I use as a dab rig. This helix chamber turns little dabs into big dabs but doesn't hurt your lungs. The chamber reduces the temperature of the dab significantly. It also expands the dab and makes it seem like a larger dab as a result. It also greatly enhances the flavor. My only complaint is that so far every nail/****** that I've put on this thing always wobbles a little bit which is scary because it greatly enhances the height of my upright rig and makes it less structurally stable as a result.
