Right I have a Tornado Tank and my gf liked it so she got one although she bought lots of chocolate type flavours. She was complaining about the after taste though and on trying hers, I do agree there is a "burning" taste. In fact its plain horrible.
Proved it tonight by putting her capsule in my tank and it smokes fine with no nasty aftertaste at all although I don;t really like her choice of flavours.
Both her atomisers taste horrible and burnt. Whats wrong? Just bad ones? Both of mine are fine.
This sounds like it wasn't wicking properly. That flavour can go over time as long as you keep juice on it, but usually it lingers ever so slightly. If the taste doesn't go, either bin it or boil it. I had the same thing happen when it went off in my pocket and it tasted rough for days
