Hi there! I've been a long time smoker. Went to a shop yesterday but not sure I got what's best for me starting out? bought an istick 20w with an Aspire clearomizer. My concern is is this going to be an easy portable solution that I can throw in my bag and go or should I use a more cig style for on the fly? My cartomizer leaked all over yesterday which made me panick even more, not sure this is best for work, travel and convenience?
