as for vg affecting chest/lungs it seems it depends on source or producer of vg.
i diy my juice, when i was using life brand vg it did make my chest feel "heavy", for the lack of a better word, when mixing high vg juices.
i then ordered a gallon(4liters) from coop coco and i didnt get that heavy feeling. maybe its just in my head idk.
info on Vegetable glycerine: certified GMO free, pharmaceutical grade (USP) and kosher,
Origin: Coconut
Glycerin, vegetable source USP | Coop Coco
imo, ymmv
What I was using at the time was what I had purchased from AVEJuice that was in their Boba's Bounty and Gryphons Breath High VG blends, but when I started using a 50/50 MBV base (where ever their VG/PG was sourced from) along with my Nic solution when I started to DIY I noticed an immediate difference, for the better. Now I am about ready to start using some ED VG/PG, so I will see how that works out, but I do like a 65/35 PG/VG ratio now (especially during these Minnesota winters). I know some like the Coconut based VG/PG better than some of the other bases, but I haven't tried that yet.
This got WAY off track, I apologize for that.
I do love my mini though, and will venture into TC at some point in time, but for the price, the VTC mini and the Cuboid make Great Kanthal/Power devices. I am using a Cuboid/Lemo V1 as I type, with a VTC mini/Aromamizer SC-200 in the next room. Very Happy Vaper !!
