I feel like I keep trying to put out this fire in every
thread that raises the topic, in hopes of saving some of you from potentially trashing your atomizers. ;-)
I've noticed this: with certain attys - depending on where they're from and how they're built, 'dry burning' can result in burning up the fiber glass wick underneath the mesh material. So be careful. I myself tried this on two different types of 801 atomizers (the BE112 and a Rocky Mountain Vapor 801), and both of them were rendered unusable after attempting a dry burn. No amount of cleaning after the fact would remedy this.
So, be careful. I myself am never doing it again, that's for sure. YMMV, of course. =]
