I love this thing. It's great. Bottom line. However, I got mine for $50 at a local headshop. So find it somewhere else!

Glass to Glass Tank Ground fittings seem to be 99.9% to 100%....Airtight, perhaps an improvement in workmanship from the other buyers, buying experience...This was a concern to me because a leaky Bong is a pain in the ass, mine is solid airtight, but I do have a suggestion to (ANY) Bong User that has the newer tank ground glass connections, it is UNWISE to "Cram, Tap and Force" any glass fitting into place seeking a "Super Seal", you are asking for your pipe to crack if you do this...may I suggest some thicker (CRISCO) paste vegetable type oil on problem leaky seals to make them more airtight (This is only a suggestion), I am no Bong Expert. Great workmanship for the money, the Uptube is plenty think and strong, the Beaker Bottom seems very "Flat Footed" and stands surely without any rocking or sway, and is only slightly thinner glass...For the Money a lot of Quality Bong..... NUMBFACE

Pro's:
-Great overall quality
-Downstem goes far underwater (more of a cooling effect)
-Strong glass joint that meets bong at a close to parallel angle
-Long thick neck with ice notches allows for insane cooling and condensing of smoke
-Diffuser has 6 slits for smaller bubbles
-So easy to clean due to lack of percolators
-Stable and scientific beaker base
-Perfectly clear with no labels!!! stay classy San Diego

Con's:
-The beaker is thick, probably 3-4mm thick, but it is not 5mm thick like the neck is
-Glass joint is only like 99% airtight (good, but could be better)

This bong is of good quality but it is not superb like a roor is. The quality is however superb when you consider the price of this bong compared to others. I like it because the glass is perfectly clear with no stupid labels. Cools smoke very well with ice especially. Very easy to clean. Shipped very fast.
