The only ZEN I own is the ZAU....for now. And I love it. I don't have a leak problem unless I lay it on it's side. I have been using a heavy-bottom beer glass lined with a papertowel or soft cloth to stand it up-right. But, take a look at this! A friend ordered one for me and I should have it by the weekend! I'm so excited!
This guy custom makes these. And, what I love about this one (BTW, he named this one "MissEmma" because it was somewhat her design, I think. LOL) that "stand" on the front....comes out and you can use it by itself! How cool is that!
Everytime I set my ZAU down somewhere, I am paranoid that it will fall over and break...and putting it into that beer glass....it "clinks" which also makes me worry about scratching or breaking. Jeeze.
