Lack of consistently performing gear almost drove me back to the cigs at first. I tried nearly all the clearos available at the time. "You got to try the <insert recommended solution to all my issues>, man!" I bought it and tried it. All the same. Dry hits, flooding, gurgling, lack of vapor, lack of flavor, plasticy taste, vapers tongue... I could leave a perfectly working setup over night and wake up to having to fiddle and clean and fix. Changing heads or even changing the entire clearo didnt't necessarily help, and was as best a very temporary fix. Was on the carto tanks for a while, but didn't really like it. A matter or taste, vapor production and personal preferences. Still, lots more reliable than any clearo I tried.
The last thing you want to do when you crave a cig and substitute with a vape, is to have to fiddle with your gear. Not healthy for ones sanity or nerves.
Luckily, when I did succumb and lit up a cig, I found I no longer liked it at all. Only solution was to find a properly reliable setup I could simply pick up and vape without thinking about it. So, I decided to force myself to set up rebuildables with mesh wicks. If for nothing else, the only one to blame for it not working would be me. Takes a good bit of fiddling to learn, but well worth the effort for me. All the fiddling is in advance, not when you need a vape.
Now I'm one happy camper with a handful of rebuildables that "just work"; day after day, morning after morning. I have no desire whatsoever for cigs.
