Smoktech Aro Clearomizer
The Aro produces great vapor and doesn't suffer from leakage issues associated with many other tanks in this price range. It comes with a 1.8ohm coil installed.
Available in either Black or Silver, use the drop down menu to select your colour.
Coils are no longer available for this clearomizer, hence why they are marked down from $6.95 to $2.95. At that price you can just replace the whole unit.
