So, I've gone through all 5 of mine.
The first one I filled to a level that I thought that was appropriate and it tasted like burning.. so I let it sit for a couple days because I didn't want to bother with it and come to find that it's leaked all over my counter.
I tried a second one today, and tried to leave no air bubbles in the chamber since I figured that I underfilled the first one, and it worked great for about 2 or 3 pulls before it started to taste like burning too..
The third one I tried to fill the ceramic cup broke when I was trying to get the seal off of it. Worked okay, but leaked juice everywhere.
The fourth one I underfilled a bit because I thought that I was maybe overfilling the others and it tasted like burning.
Threw the fifth one away because I was tired of wasting juice.
After reading all of these posts I must have been doing something wrong, but after watching the videos and reading around I don't see what I was doing wrong.
The o ring on all four of mine was melted and distorted and the wick was completely charred.
I'm using regular ol' KR808 batteries here with 2.8-3.0 ohm clearomizers, was I just using the wrong ones or something? I feel like I wasted a whole lot of money with this experiment
I'm also not too pleased that I was probably inhaling some plastic byproduct with the melting o-rings
