It's proven to me
but everyone should make up their own mind.
I was apprehensive about cleaning two-month old atomizers with the dry burn, but I think the step of an ultrasonic cleaning before the dry burn helped me, or I was just lucky. I haven't lost a used atomizer yet. When I started doing it, I cleaned 6 used atomizers using an ultrasound clean/dry burn/ultrasound clean cycle and didn't lose any.
The second ultrasound cleaning removes the burnt taste the dry burn gives my atomizers. I can see some ash and black bits after the dry burn that are gone after the second ultrasound and the burnt taste is gone, so I'm sticking with it.
My oldest 510 atomizers are over 6 months old. Both still test at 2.3 ohms.
It's working for me, is easy to do (takes less than 5 minutes of my time, but 2-3 days total time), and gives an atomizer that tastes and works like new, and looks functionally nearly like new.
The ultrasound does fleck off the black paint, so the outside of my atomizers looks crappy unless I finish removing all the paint, but that's the only drawback I've found.
