2clicker: Next time you're ordering yourself more Nano's from GotVapes, order a couple (they come in a two pack) of Sapphire clearos. I've been using both, and I prefer the Sapphires because they work better both with undiluted Pure Gold and 50% mix with PG (glycol, not gold), and they never leak, even on airplanes. They also last longer and taste much better. Inside the bottom core (which you can't see in either without destructive deconstruction), the Nano has filler material packed in tight, surrounding the coil and wick, while the Sapphire just has a wick and the coil, which is why the Sapphire tastes better, I think, (and it has less wasted in the "priming" part, which you lose when you finally throw the clearo out). The Nano's do have a little easier draw, and a nice round mouthpiece, both characteristics which I actually prefer to the Sapphire's tighter draw and duck bill mouthpiece, but it's a real horse race and totally a matter of preference. The Sapphire is also easier to fill, and I've stopped using the Nano's (i have two left to play with). I think either is a very good choice to be used with liquidizer extractions mixed with their ejuice.
