Please note when using Justfog Q16!

  • The coil can be damaged if it is not sufficiently wet with e-liquid.

Hold the clearomizer up for 2 minis until the coil is sufficiently wet.
Refill the e-liquid before the tank is completely empty.

My vaping experience

Justfog Q16 is a delicate and portable small kit. So it is very convenient to carry specially when you go out. Unluckily, due to the internal structure of the Clearomizer, it is easy to leak e-liquid. Although Q16PRO battery has a smooth body, once it gets water or oil, it can easily slip from the hand.

All in all, after learning the user manual, I hope everyone has a good vaping time!
