This is a tool. It is made with some precision, but also some touching flaws that make it human. The glass around the bowl is a little bulged towards the right, and the bowl is not perfectly pointed down the center. This to me is not a serious flaw, but one that suggests that a human had some part in its production, which makes me smile. Its design is extremely effective while remaining an interesting piece without any wasted glass.
The reservoir is exactly what I wished, though I could imagine someone wishing for something larger. This, however, is plenty in my experience.
I don't feel I've cashed a bowl on accident too early, or found myself faced with airflow problems with a normal pack, and the bowl is small enough but accommodating enough for several hits to one or two, a real goldilocks bowl, this one.
Plus, it looks cool as ****.
