Well,
Got mine in today, LOVE it...
It's bigger and heavier than the VT40 that's been my ADV for the last 6mo, but compact enough that it fits comfortably in a jean pocket beside my wallet. (Jeans are my every day attire, and I don't wear hipster skinny jeans, just normal grown man pants

) Note 4 in once pocket, wallet/30ml
juice/device in the other pocket... It's how I've been doing it for years. It's not appreciably heavier than my old VTR, and more compact than it or a vape flask clone.
The hobbyist in my loves the Escribe functionality which gives an inside look into how things are working, but the practical side of me knows that once I've got things dialed in I'll likely not use it much.
It's my first day, and I'm sure I'll learn more, but overall I'm very pleased with it. For those that already own DNA200 devices, this is old news, for those on the fence, GO FOR IT!!!
Thanks for the helpful links to the poster above, I used these and will run the case analyzer soon myself.
Cheers
Edit to add, man is this ever comfortable in the hand. If I feel the need for a cheap backup I might get a RX, depending on how the wifes VTC mini works out (similar
joyetech chips and all...)
