All the folks trying this clearo or that topper, and having problems and not liking the taste...
I've converted to using tanks like from IBTanked, and either BOGE or SMOK prepunched cartos. Watch for and buy the cartos in bulk, and save. A fresh carto may last a couple of weeks, or die in a day - but, hot-swapping in a fresh carto is easy, and zero problems. Great flavor, no weird taste, no weird draw issues, no gurgling or flooding issues - for just wanting to vape, all I can say is WOW~!
The key is making sure the carto is full of juice (not dry) when you start - IBTanked sells their tanks in a 'thingy' - which is a super easy 2 minute way to fill a carto, and/or carry a spare tank filled and ready to vape. It's just sweet.
Then, if you like, you go start collecting all the sweet tanks on the market like the SnP, etc (or not).
