I don't want to be negative, but between me, my mom, and best friend we have 15-20 iClear 16's (came with starter kits). Every single one stopped working in short order...and they never really vaped well to begin with. I HIGHLY suggest picking up something like a Kanger mini Protank 2 and a pack of extra coils. You'll be amazed at how much of a better vaping experience it is.
