ADabLDo loves this Glass Bubbler Atomizer. It has Dual Ceramic Coils and the standard 510 EGO Thread to fit most batteries. Put about about 7 ml ounce of water into the mouthpiece and vape away. You will experience a smooth draw with maximum effect. You do not need to cough to get off with this guy. For the price you can not beat the quality. Tip #1: Do not blow through the globe, you will blow water into your atomizer tray.
