Q1: Why there is a burnt taste after several puffs?
A: Please make sure you have soaked atomizer heads adequately. You can drip a few drops of e-juice into the atomizer head directly before first use. And if the VG content is too high, it will easily bring burnt taste, so the e-juice should not be too sticky.
Q2: What could we do if the atomizer leaks from the mouthpiece or atomizer base?
A: If the liquid is leaking from mouthpiece, firstly, please make sure the e-liquid was not filled into the air pipe. Secondly, please check if the sealing O-rings on the atomizer tube and atomizer head are both intact and in good condition. If the liquid is leaking from the atomizer base, please check if the sealing o-rings on the atomizer base is intact and in good condition and make sure the liquid level is between 10%-90%. Also you must make sure all parts of the atomizer are assembled tightly.
