I was looking around last night and ran across this, NCR New concept RDA. It looks very interesting to me. It is saying it has a 600,00 cycle life and you can dry burn to clean the “wafer”. The “wafer” is made out of SST aluminum nitride Just fold over the cotton on the “wafer” and that is it. It has a resistance of 0.4-0.5 ohm. It is suggests you use a power curve with it. Not sure if there are other resistances available. I didn’t look. Has anyone got to try one of these? Any thoughts, as it is a very interesting concept.
