Interesting idea about the rolled up paper towel... I'd like to try cotton wick at some point, but it's good to know there are common household items that can be used as a wick in a pinch!
Thanks to a bit of tinkering and the advice from you kind folks, I'm becoming more impressed with and even amazed by the nova. It's not the same as dripping in an atomizer, but it's nearly as good tasting, and in one respect, even better (for me) in that I've never been able to get *consistent* performance from an atty when dripping, without cleaning out the effing battery connector all the time, and waiting for it to cool -- the nova is now giving me that.
I'd yet to work up the courage to try dry burning with any devices, since I've always been concerned with frying something. But after trimming the wicks so they only reach about half way down the tank, cleaning the 1.8 head in vodka, and then dry burning a few times, re-wetting with vodka in between dry burns, and blowing the crud off the coil... then filling and vaping at 3.3 volts:
Oh. My. God.
Every hit is almost perfect in flavor, it's wicking like a champ, and has been tasting incredible for about 10 hours. There's a little variation in flavor and vapor when vaping heavily, and I have to go up to 4 volts or so to get big TH, but that seems to bum out the juice I'm using a bit, but I don't want a giant throat hit anyway, so for now, low voltage it is for me.
The novas seem to need a little tinkering, mostly just cleaning, and they positively beckon experimentation, and offer the possibility of practically cost-free operation, so if, like me, you're kind of in to that sort of thing, you might quite like the nova.
If they can make a future version that works this well out of the box, I think they'll sell quite a few. I wouldn't even mind paying a little for somewhat increased build quality.
Honest to god, I'm not trying to advertize these things for them, but as a still new-user, I just think these things are the best vaping device ever, after messing with cartos and atomizers for 2 months, I was 100% ready for this.
