Please make sure to leave the atomizer alone for at least 1-2 minutes after injection or just drip a few drops e-juice directly to atomizer coil head so as to make the wick
inside fully moist. Also you can inhale for several times without pressing the button.Don’t puff too long one time, stop puffing when the e-juice is not enough, clean the coil 
when it begin splashed.Also pls do not use very high VG content (means too sticky e-juice),which will easily bring burnt taste.
