I haven’t used mine in a while but never had issues with dry hits. I did have some leaking though. I ended up putting it in storage after not figuring out the leaking. I seem to remember it was better if I didn’t use both airflow openings.My Fat Rabbit is giving me problems. First, I couldn't get the build deck separated. In fact I put it aside for several months because of that. I came back to it and using pliers, got it separated. My first two builds, I kept getting dry hits, so this time I cut back on the cotton and now it leaks. My solution? I just closed the upper af. Next time I rewick it, I'll try for the Goldilocks amount of cotton, but for now, it'll do.
