The Z-Atty pro is too much work.
reviews also say it leaks like a sieve. I don't want to re-build anything, just toss out a bad coil/wick, and replace. Kayfun- same thing. Can't tell if the Penelope has replaceable parts, or if I have to cut wicks and mess around with coils. I really want to find a glass or quartz top coil clearomizer with replaceable coil heads before I buy a ProVari, but it seems no one makes one yet.
