Not to worry (too much). The Stick is not completely sealed (very few, if any, PVs are). If you overfill it, or use
juice with a low viscosity, or perform any number of random kind of things, it's possible to get this leaking, I suspect, even with a V2. It IS possible, and even pretty easy (see the video posted in the forums) to get it apart and clean it. I have not yet been able to get Janty to make a clear statement about warranty coverage for doing this, but the end result seems to be that if you take it apart and clean it and put it back together with reasonable care, nobody will be able to tell you did, so no warranty issues. At any rate, the leakage is more annoying than anything, I've never heard yet that leakage resulted in a failure. Good luck.
