burned my spare Kangertech atomizer a few weeks ago(forgot it was a 10-25v while the one i'd been using was a 15-50) so I've been using my old O2Pur until my penny jar filled up, and holy crap, there's no comparison and no going back. This piece of kit i found to be such a wonderful upgrade from the disposable and cartridge e-cigs I started with now feels equally inferior compared to my Nano. Seems like everything I get into is like that. I better stay the heck away from the real top-shelf vapes. The one's that look like a cross between a lightsaber and a sonic screwdriver sure are sexy, but they also start at 2-3 times what i paid for my Nano, which though fairly utilitarian has all the functionality i can imagine myself needing or wanting. Kinda like a Merkur HD vs a Feather SS. Now let's see if I can get myself in trouble with some exotic juices too!
