As much as I enjoy tinkering with my rebuildables, when I'm working my 12 hour shifts I have a 96 hour period of time when I haven't got the time or energy to sort out
vaping issues, wrap new coils, wash out tanks etc. I have to have something that I can pick up and vape with zero maintenance, which will work flawlessly every single time, with no flooding issues or problems whatsoever, and whatever solution that would be, it would have to perform really well, with outstanding flavour and vapour production. It would have to be transportable, with the risk that it might end up upside down in my bag with zero leaks,
And so I'm a cartotank-aholic too. I can get a cartomiser to last me a fortnight now, and yeah there was a learnning curve to go through with how best to punch them and how best to prime them, but once you've learned that really it's all plain sailing with them. My cartotanks outperform any other non-rebuildable atomiser I've ever tried. I only ever tried a cartrotank as an experiment to see what all the fuss was about, and never looked back. In fact, if I have an e-liquid that I particularly prize, I will put it through the cartotank as a preference to any other of my atomisers. That says enough about how highly I regard them
