Bottom coil MT3 cartomizers provide a nice warm vapor, with a awesome clean flavor, and reduced wicking issues. Unlike other Cartomizers, the mouthpiece of the MT3 is permanently attached and it is filled from the bottom. This two-piece design is a really big advantage over other hardware with replaceable atomizer heads. With the MT3 if the atomizer head fails when you least expect it and the tank is filled with ejuice, the atomizer head (base) can be easily replaced without the need to drain the ejuice in the tank first. The Cartomizers is filled by simply turning the tank upside down, unscrew the bottom cap, add your favorite LeCig ejuice (straight from the bottle) to the fill level (top of the inner metal tube) and replace the cap. Plus, it has a window so you can see your juice level, which is a really nice feature.
Works with MT3 kits, H2 Kits, and all Tanks.
