Thank you, MeowMix. I had bought a couple of Clearomizers with my kit, but hadn't used them yet. I filled one this morning and it was much, much easier than a carto. My sales rep had told me to turn it upside down every few puffs, so I've been doing that. I'm going to stick with the Clears for awhile since, for me, it is taking the guesswork out of this. I'm just coming off analogs, so I really can't deal with much vaping failure at this point. I'm keeping a close eye on my fill level and making sure it stays between 1/2 and 3/4s. I'll see how it goes today.
