Yeah Florduh helped me out with the use case. I guess I am just not used to having to hide the smell of my cannabis since I mainly vape at home or on walks/hikes.It's a lot quicker to just open one jar, load my dynavap, and close the jar then vape, than it is to deal with opening the bell jar I've got everything in, pull out grinder, unscrew grinder, put grinder away, close bell jar. That and grinding, in my experience, is the smelliest part of the whole thing.
Having my meds preground in the classic for the week cuts out a lot of smell and excess time.
Edit I concur @florduh
