New laws mean only 2ml tanks are allowed. We tweeted about some we got but decided a review was not worthy and instead review the new pod systems.
Tanks come in various desings, from the first clearomizer, to bigger 3 - 5ml tanks.
Clearomizers cam top fil and sme bottom fill. Where as tanks came bottom fill, but are currently making way in Top Fill versions.
Other features now eliminate leaking isues, and there could be other advances as time goes on.
