I've just received the latest VS rDNA40 from Vapekulture (sent my old one back due to screen bug & waited for the latest revision). I've also played around with my friend's SX Mini M. Now what Im about to say may be incorrect but the previously absent atty lock on the VS is similar to setting the ohm on SX Mini M. The concept for me are more or less similar. But since I didnt get to play around with the SX Mini M that much, the joule is something I'd love to actually understand. And being really familiar with DNA30, the rDNA40 felt more like home. I do however have the SX Mini M on my wishlist unless I manage to get a jackpot to get one of the infamous bangsawan mods, lel.

No idea of any other TC mod. HB got few bashes here & there albeit it being said to house authentic chip & all. IPV4 like the SX Mini M is only out for public for some time so I guess time will tell?

Yeah Joule was for the temp control..

lol I have no idea, as I said in my previous reply that I wished to actually understand Joule. All I know was when I played around with the sx mini m in temp control, the unit is in Joule rather than watt. Thats what I mean. I seriously have no idea of how Joule controls the tc if it does? I should watch pbusardo's review on this lol.
