This is a 20/10 bong. It arrived less than a week after I bought it, even though they had a warning about shipping delays due to the pandemic. The included downstem was shattered when I opened the package, so I emailed the 420 Science customer service and they sent me a new downstem for FREE that was 3x the price of the original one AND had a nice perc. The glass of the bong is really thick at the beaker base and tube but a lot thinner at the joint that accepts the bowl so be careful with that weak point. My only complaint about the bong is that the circumference of the mouth piece is a bit large which took some getting used to but maybe that's just a preference? I've whacked the beaker base of this bong on all sorts of counters, tables, railings, walls, you name it. Somehow, it has never cracked or chipped. It also cleans easily and the ice catcher is a nice extra. Buy this bong, you won't regret :)

pretty cool piece. fast shipping

It was great but I didn’t get the bowl that was shown in the picture but other than that excellent

This bong or water pipe whatever you want to call it is a solid piece. This is my 3rd water pipe and by far my favorite the ice pinch works very well and the beaker itself holds a good amount of water for great filtration.
