In another post I mentioned that I bought the Janty Neo and loved it. Unfortunately, I'm having problems with the puromizers in that they just don't produce vapor like they used to. I've been using them for two weeks. I did start with the Janty pq liquid, but then bought a sampler package of Crystal Liquid in 100 pg. I did find that they varied in viscosity and one of them was really viscous and I think that's when the puromizers just simply failed. I blew out the liquid and put the Janty liquid back in and they started working again, however, they are just petering out on me again. Are they just gone...is this it? Any advice would be appreciated. Thanks.
