I would be interested to know though how much you feel the RX200 is giving you the vape you want compared to the DNA200 variant after having used it for a while, and if the lack of Escribe functionality is actually that much limiting to having an enjoyable vape.
I have the RX200 (not S) and a handful of other mods.
I recently bought an HCigar VT133, dual 18650 DNA200 chip.
I can say after a couple of weeks that the VT133 outperforms any other mod I own using the same tanks, coils, juice, and batteries.
Much smoother vape, better battery life.
While I have used the Escribe software to set it up and to calibrate the case thermals, once I put the material I use, TC settings (watts, preheat, punch), I haven't used it again. I do play with it from time to time. Kinda cool to watch the device while vaping.
Having said that, I am unsure if it is the chipset and mod build or the Escribe software that produces the vape I get. I've seen some other DNA 200 unit threads and battery life was not what they wanted. Of course that was with LIPOs.
As a long time Yihi user, I was VERY surprised at how much better my vaping is on the DNA200, specifically the VT133.
