They're small, portable and the easiest pieces to clean (clean pieces give better and longer lasting highs) a qtip can clean every part of it. They also hit pretty hard and are so small you can act as if you're smoking a cigarette by covering one side as if you're lighitibg a cig in the wind. I've toked up many times in public with them
Every piece has its own function and peoples needs are different. I think sublimator is one of the best.
Dug outs are the shit tho. Always come in handy for stealth. Sent from my LGLS620 using Grasscity Forum mobile app
