The Kanger MT3 clearomizer is the big brother (and inspiration) for the Kanger Evod.
The design is almost identical except that the MT3 is the predecessor to the Evod, and is much larger. The MT3 is a bottom fed unit with replaceable coil heads.
A well-thought out feature of all Kanger bottom fed tanks is that you can replace the coil without emptying the liquid. This unit attaches to the outer cone threads of an eGo battery and is not 510 threaded.
A 510 to eGo adapter can be used to attach this atomizer to a mod, or any battery which is non-eGo type.
