After reading through some of the more recent comments, I wanted to chime in and see if anyone else is experiencing an issue I've run into with the FITT. My FITT arrived about a week ago. I waited until the "Empty Pod" Starter Pack was available, because like many of you, I prefer making my own juice. If it's not salt-based, I'm not interested. I also purchased the 4-pack of empty pods. As soon as the device arrived, I loaded three pods up with some new flavors I was trying. The new mixes needed work, but the device was solid. Coming from a JUUL and MyJet, I was loving the larger battery and tank. Then I neared the end of the pods and I started getting burnt hits. I think I've figured this out, as it seems to be tied to excess fluid at the contact sites of the pod. Not entirely sure that's the cause, but that's what I've been leaning on lately. The odd thing that I've run into is that the 6-second kill switch (~Aquamarine light) doesn't seem to work consistently on a re-filled pod; particularly one that I used the FITT to clean via the button-burnoff method. If I'm not careful, I get a horrible hit that burns like hell and tastes just as bad. As to the leaking, nearing the end of fill #2, I can attest to that issue being present on the latest device / empty pods. Seems like it is more likely to occur if I put the device in my pocket, or if it spends a significant amount of time in any position other then standing upright on a level surface. I just ordered some premade coils to see if the kill-switch for "inhale" mode will come back with a fresh coil. This is certainly an improvement over the MyJet, but I am more careful with the FITT than I planned on.. Also, for any new user that might read this, avoid using any "fast-charge" USB connections with the FITT. I don't think I've harmed the device by charging with the same charger I use with my gs6, but the FITT reports a full charge and then goes from Green to Red in less than half a day, without any time spent in the Yellow phase.
