I hear you. I recently tried a Kanger and really enjoyed it flavour wise and warmth wise, perhaps I'll have to switch

I can't say anything about their longevity though because I lost the only damn one I had (with it's drip tip!), which was given to me at a vape meet. Doh!
BTW, please check out my questions in the Pre-punched Smok thread. I think I broke my carto trying to cut the coil?
