I vape a lot of cinnamon (R.I.P. mini nova, clearos, acrylic caps). I didn't want a metal sleeve for the nova because I couldn't see the juice. I saw the Neptune (a.k.a. Vision STV Vivi Nova) last night and thought "Oh Cool!" Luckily I read the description before I bought one. The clear part is PC (polycarbonate), which is incompatible with cinnamon (and quite a few other e-liquids). It makes no sense to me that they didn't use polypropylene, since I think many people use the metal tanks because of the melting problems with the plastic ones.
"...incorporates a windowed metal sleeve so you have the protection and style of the metal tubes overlayed over a PC tube and with a large window to see your juice level!"
Oh, I get it - it's decorative.
