I have a eGo which is what I use most of the time but I bought a volt sealed batt and these cartos to have a cig look-a-like for partys and social events
It is really hard the find a carto that looks like a cig filter!
There is tons of recommendations for this product and it's really simple to use much like the one you have other than theres a button to press to fire the delivery device your using.
