If you get a whistling, high pitched sound, or similar sound when you inhale on the
electronic cigarette, this is completely normal with a fresh
cartridge and brand new unit and is the sound of the air being drawn in through the sides of the
atomizer during inhalation. After you first receive your ProSmoke
electronic cigarette and start to use the unit, there will be a slight break in period for the
atomizer that will eventually give you the smooth, literal draw of a traditional 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, and quietest, draw until its fully broken in.
As the atomizer breaks in, you will notice it will be much quieter with better throat hits, more vapor, more flavor and an easier draw! Typically a break in should only take an hour or less of ACTUAL USAGE total.
