Pro-Tank 2 came in the mail today and, by far, it beats out the iClear30s and Vivi Novas I own. Its already survived a 3 foot fall on hard wood floors (thank my dog). But I keep getting this wretched chemical taste. It isn't consistent, sometimes I'll get an excellent vape. It is common enough for me to set it down until I can (hopefully) resolve this issue. Things I've tried: Rinsed and soaked all the parts, excluding the atomizer, in hot water. Let it soak upright with a full tank for 2+ hours. Continue vaping, hoping the taste would go away. This makes me think that its the atomizer. I don't know how to clean (or if I can) the atomizer. I'm relatively new to vaping and brand new to Kanger and bottom fed clearomizers, so its probably something quite obvious.
