Have you tried a glass mouthpiece with the POTV One? And have you tried cleaning it/doing burn offs?
Unfortunately yes.
I've tried it with the bent glass mouth piece and the mini curved bubbler. I've done ~15 - 20 full temp burn offs. I could never get it to have a neutral taste / smell before using it so I decided to see if it would disappear after using it. However, quite a few uses later, I still catch an odd silicone flavor. Usually near the end of a bowl - which makes me think the herb is just masking the taste.
I'm not saying there's a health issue with the vape, and chances are I'm just really sensitive to either the silicone gasket or something else used in its construction. It's just that I'm not personally comfortable using it daily, long term. For the occasional use I'll most likely keep it charged. At least until I get a different portable.
I've also found several other people complaining about taste / smell with the Fury 2 which I believe uses the same gasket material (different metal screen) so I'm
pretty sure I'm not just being paranoid.
I'm glad that I won't have to worry about any plastics in the E-Nano air path.
Edit: I haven't tried using the stock Fury 2 style mouth piece. I wonder if it's something in the accessory adapter? Something I'll have to play with tomorrow after giving it another cleaning.
