For me, I always want more. Something about the addictive nature of nicotine, for me. I believe many other vapers are like me. Started with cigalikes, then mini ego clearos, then a dual-coil (oooh two coils) and so on, and at every stop along the way, I was sure "this is it!" Then I'd try something new, a subohm tank, then a bigger mod for higher wattage, then RDAs. Then DIY liquid making because those tanks and RDAs drink juice. I honestly hope I never find a need for more than what I have, now. Hard enough to resist buying new products that already do what I want, just in a different way.
