I really love this thing, it's so very handy yet superpower-packed yet hits the lungs as light as a feather; it only needs a tiny bit of water and yet the round design eliminates sour hot spots during a smoke sesh while also helping to make cleanup with rinsing afterwards painless & carefree. The downstem has proven to be rather clogproof even after weeks & weeks of daily usage and the carefully designed spout on the bottom really helps to prevent water splashing back up towards the bowl, even with quite vigorous huffing n puffing. As always, Grav stocks replacement bowls that fit perfectly with this bubbler body, which means you can spend more time enjoying your session and less time worrying about cleanup afterwards or even accidental drops. Wish Grav sold some kind of carry pouch/case but for now a rather boxy padded pencil/stationery case is working out quite handily. A new classic in my book!
