When I didn't use the channels, all my liquid came out of the air holes. I emptied 2 tanks of juice, but I wasn't using the bottom fill hole. I was holding the glass, filling from the top, and then screwing it together. It's working now, but it doesn't hit/taste as good as my Magneto RSST or my Kraken. Both of those have a single microcoil at 1 ohm. Not sure if having two coils sub-ohm strains the flavor?
