OK not much to this post I'm using a rebranded ego and have been using the cartos I got with it till they all just quit working. Been looking at the mini Nova for sometime and thought why not this payday well crap guys I don't think I'll ever go back to a carto it's just that much better. Could have been the ones I was using but don't matter much to me this set up is going to stick around for quite sometime. I was even looking into getting a new mod as I thought mine was just under powered but Eh just saved a few hundred bucks!
