I just went and googled both mod and tank------wow this smaller form factor is fun and is a welcomed change from all the big 22 mm tanks
and tube mods----am getting sick of all the 25 cent piece size modding.
using this rite now and am fascinated by the small size and vapor/flavor that you can achieve with less size...this is the Smok Dripper RDA 14 mm in size about the same as aego battery......
