This thing is amazing. It has great airflow, and a nice low water line. It is not a mini-rig; more of a full-sized rig. Is it better than GRAV Orbis for dabs? It's hard to say. I really like how grav labs does the mouthpiece on their Orbis line. Its made by "ICON" an alternate line from "Diamond Glass," which isn't exactly ROOR quality, however this slush cup has a fantastic design, good percolation and watching the smoke rise to the top of the slush cup is beautiful. It is sturdy, not hard to clean, and the slime accents are dope. Is it worth twice the price of GRAV labs slush cup? Maybe. Just know that this little thing can stack smoke like a champ and has versatility. The showerhead perc gives it low drag which work great with low water line minimal water setup for dabs. There is a small expansion right below where the 14mm bowl sits where the smoke stacks that seems to help out a lot. The design is smart. It's the piece I use the most.
