I’ve mixed this with 4 different dabomizers to milky finishes! Clean rips even 2 cleanings later. Cleaning is also wicked simple. A superb piece in my collection.

I have both the 14mm and the 18mm. They are equally well made and very thick glass. Paired with the DT V4 it absolutely rips, but at the same time delievers an extremly cool and smooth hit. I keep mine right in the door of the refrigerator for once chilled hits. Must have

I have had my DTV4 and Hubble Bubble for almost 2 years and the polished SiC for a little over a year and the SiC is the best crucible out of them all. I even have a bottomless banger and rig, but I mostly have used the Hubble Bubble and I can say without a doubt that the 18mm Hydrotube is so much better than the Hubble Bubble and it hits just like the bottomless banger if not better! The Hubble Bubble is nice for in the go but the Hydrotube is great for home use and the glass base is a great addition to the Hydrotube! I’m glad I got the 18mm Hydrotube it’s bigger than the 14mm and gives milky clouds! This Purple Punch hash rosin tastes great out of the DTV4 and Hydrotube!
