I just set up mine the same way I would a regular CE2, filled it, primed it, let it rest a bit, and it taste weird, not like primer, an unpleasant burnt flavor that does not seem to go away. I put a couple of drops on the coil itself, and let it sit a while so the wick would get saturate, tipped it upside down a few times, all the tricks I know... I don't know if this is part of the defect causing this, or if I can get a replacement when the new upgraded ones get in, as I can see that being costly for you to just give them to all of us who already ordered, but I am not at all happy with this over my regular CE2s. It's too bad, I was really excited to get this. Maybe I just got a bad one... I know it happens from time to time. The funny thing is I have not had one problem with the CE2s no matter which ones I have tried.
