I have now tried 3 totally different juices on this ZAP and have determined that I'm getting no taste and therefore I have a definite wicking problem. I guess it's time to roll my own before I give up.
Fran - how about testing your 'wicking theory' by diluting a bit of your juice w/ 10-20% distilled water. That should thin it down and at least see if it wicks better.
When you put you wicks in - to they fit loosely. If they're a tight or snug fit it will interfere wicking.
