Kanger bottom coils were a game changer for me. As someone who hated every carto - in or out of a tank - I ever ran across I was stuck at "atty" until the Kanger T3 showed up. I tried top coil stuff - T4's etc. and Vivi Novas - but found them both annoying and underwhelming. A Kanger bottom coil is one of the easier things for a Newbie to figure out and get a long lasting consistent vape. Are they lighter on flavor than cartos? For most people - yes. But you pick your fights and you pick your compromises in this game.
