Each puff becomes a whole new experience. One tank it brings the nostalgia of cola with hints of green apple. The next tank it morphs into a tropical slushie with hints of pineapple and fruit syrups. In any case, ive been vaping for a long time and have searched high and low. This is the only liquid i have ever bought that i can and have vaped non stop for entire weeks and never get tired. Will be trying all others in this line of liquids.
