Yes, you can change the E2 cartomizer with the Pre-Cut E2.
I have asked Stormy to give the details on how to do it.
Fits best on a bigger mod.... Are you meaning look-wise or functionality? I was thinking of using the MapTank on a 5v passthrough, or just using it around the house so I don't care about looks.
Still looking for an answer to my question. Guess it was overlooked.
If you don't care about looks, yes it will work. It will work with any device that doesn't have a top push button I believe. If I'm wrong about this, someone correct me.
