recently, I "thought" I had a problem with AVE juice ... Ben replaced the juice ... after testing, steeping, more testing, I concluded it was definitely NOT the juice, nothing wrong with it all ... so I apologize to you Ben ... I agree, it is rarely the juice that is problematic
re: Vivi Novas, they definitely change the taste imho, I've tried a lot of clearomizers over the years, they've all had issues, the common issue being muted taste, burnt taste or different taste ... I can use the same mod, same wattage, comparable voltage of course, different ohm heads, same juice, and the v2.5 Vivi Novas taste is not near as flavorful as a standard Boge, either alone or inside a pyrex tank
I am not a dripper and the ONLY reason I recently purchased the Vivi Nova was to use with nets (naturally extracted tobaccos) which clog carts quickly, even the cleaner nets ... I've had some nets I really like, but they clog a Boge after 5-6 mls ... other, cleaner nets, I can run thru 10-12 mls ... with the Vivi Novas, so far, I get comparable vaping time, but they are easier to clean and cheaper to replace the heads, more so than throwing out and replacing several cartos ... I haven't run a lot of nets thru my Nova yet, so my opinion may change ... but my one opinion that still stands is that all the clearomizers I've tried will mute or change the juice taste ... I have tested these types of clearos against stand alone cartos or cartos inside tanks, and I've never found one yet that gives a flavorful, true taste, sometimes close, but never a ringer ... my

nets are usually far stronger than lab juices so even tho the Nova may slightly mute the taste, that may not be too bad a thing with strong, in your face naturally extracted tobacco juice ... just started testing, so no clear conclusion yet re: the VN and taste
