It is hard to inhale or draw on my electronic cigarette, is this normal at first?
When you first receive your ProSmoke electronic cigarette kit and get started you will find that it will get easier and easier to inhale as your atomizer constitutes to break in. You will continue to get more vapor, better throat hits, and easier inhalation as you continue to break in your cigarette.
Since the break in period is common with most high quality electronic cigarettes, you can do little things such as rotate the cartridge to assist in getting the easiest draw until its fully broken in.
Typical break in period is around an hour of ACTUAL usage time.
