Four feet of funkadelic self serve greatness. I wanted an acrylic piece to remind me of my high school days (yes, there was a time when a glass smoking vessel wasn’t readily available). I’m fully satisfied with the tube. It’s precisely what I wanted; I’ve owned acrylics with a glass downstem and glass bowl/slide. I didn’t want anything that could easily break, I live in a small studio apartment, so having ample space for a huge bong isn’t a thing. (I also have a dog and cat… for some reason glass bingers wouldn’t have a long life… tails wag pretty hard…) So this thing is just perfect if you’re looking for a durable, large, chugger of a bong. Sometimes this takes a vacation to my woodworking shop, and I never have to worry about injuring the device and it’s safety.
