The best things about this vape are its portability, ease of use and stealth, the replaceable batteries and its all in one with the stem being left inside.
The downsides- i'm a very light user of natures gifts and so use only very small amounts maybe once a week. Its great for me because I use a tiny amount in the stem.
to get a decent draw you need a deep long inhalation, something I dislike because it means taking particulates deeper into the lungs.
the stems are stupidly fragile and could easily be made from much tougher material - The black stem while adding to the stealth makes it harder to know what you have packed. although you can never pack too much because the bowl is tiny.
Great for being out and about, festivals, gigs etc. Great for the light user, good to share for mini sessions with friends.
I don't think it would be appreciated by a heavier more dependent user or medical user, unless you use it little and often - then you would probably also need a bunch of spare batteries as they don't last long due to needing the temperature higher to get a decent dose.
