Review of POTV XL Bubbler
★★★★★Greg BitoVerified buyerI absolutely love this for my POTV Lobo
I absolutely love this for my POTV Lobo. I was previously using a somewhat similar device sold by POTV which was OK but heavy drawers will always pull water into my mouth. This extra large bubbler eliminates that altogether. And on top of that, it is extremely easy to clean. So not only do I get a larger bubbler, and cooler vapor even with heavier draws, I get the bonus of being able to keep it clean without much effort. Love the way that the “mouthpiece” can be removed easily to empty and clean it. I “highly” recommend this for all Lobo enthusiasts!

Review of POTV Bubbler Stem
★★★★★glass_ladsolid upgrade
Didn't expect this much cooling from such a small bubbler. Easy to use, cleans fast, and feels well balanced on the device.

Connecting this to my bong couldn't be easier. Fits snug, no wobble, and the airflow is smooth straight away. Makes water sessions totally hassle free.

Review of POTV 10/14/18mm WPA (2-pack)
★★★★★glasshead_jOne adapter for everything
Love that this connects to all my water tools without needing multiple adapters. Tried it on 10mm, 14mm, and 18mm and it seals perfectly every time. Very convenient� one small gripe is there is the tiniest wobble at 10mm (not that I use that often but it is there).. 14/18mm are all fine though.

Do I need the black base?
Yes. This glass fits the compatible black base (mount) for the XMAX V3 Pro and V4 Pro and doesn't work without it. The base isn't included and we don't sell it. See what fits the XMAX.

Yes, if the joint is 10mm, 14mm or 18mm female.
How many are in the pack?
One adapter.
Does it fit both the V3 Pro and the V4 Pro?
