I agree with the anti branding on the exterior sentiment. Regarding the travel bag, I find no value in it personally. It's not going back in there beyond maybe the first week. Most accessories that come with little pouches never get put in the pouch. I don't know. If it provided some measure of protection beyond abrasions, then maybe, but at that point it seems like an option accessory (shock protection case/bag). Anyway, I don't really care much about accessories unless they solidly improve performance.
A spout attachment that locked in via magnet would be a great accessory. It seems a brush of some type would be useful to some, but again, we probably already have a bunch (unless we are a newer user). But for instance, my MFLB came with a brush, which I obviously was gentle with because the MFLB is so tiny and delicate, but the handle fell off the brush within a few weeks of regular use. I would rather not have crap break on me or clutter up my place with stuff I think I may use eventually. lol All this is my personal feelings, and is not likely to represent the masses. But I mean, as a long time vaper, I have a lot of certain things....battery caps, glass connectors and tubes, silicone sections of different diameter, brushes, crappy grinders, glass bowls for smoking, etc etc etc
