Sorry for the delay all, but Kushka very generously sent me a rn4081 and it worked perfectly in the safecig. And, in my "smoke free" that I got from the mall. (Which I think they said once a "smoke everywhere". My wife and I are almost fully converted to the 510. But, for backup I wanted to find cartos that would fit the safecig.
And the answer is YES. rn4081 = safecig = smoke free
(disclaimer... I don't know the technical specs of battery, etc... I just know the rn4081 vapes good on the safecig. i.e. it fits.
Thanks Kushka! I'm sure this will help many that were drawn in to the safecig advertising.
Now I have to look for rn4081 prefillid cartos. I'm doing great on the 510, but my wife can't find the "perfect" flavor in a prefilled carto. It's very limited on the 510. I'm hoping I can find more options with the rn4081 prefilled to get her off analogs for good. She don't want to mess with filling and/or dripping.
So, can somebody tell me who has a large variety of prefilled rn4081 ???? She likes strong coffee.
Thanks again!
