Thx for the discussion.....The ability to replace the battery easily on the fly was the main reason I've been considering it. All of my dna's are built in batteries and usually last 8 to 10 hours but I take an extra mod with me in case I need it. Just taking an extra battery serves the same purpose. The built in LED in the switch and the way it functions is also a neat and functional feature.well.. I cant speak to the differences between the VS rDNA and any other dna 30 box.. this is my first one. But the Size is perfect for me.. small! The rDNA is a lil bigger than the original VS DNA, and yet.. small. I like that. and of course the "r" factor.. the ability to not only charge the device, but carry extra charged batteries, if out and about and un able to chagre the internal. so thats the bonus with this vs the original VS.
the differences between this and the Atmos Rx Power-vape 18650 vv mod I originally had are big. I believe the power-vape must use PWM, where the VS is steady power. meaning it heats faster and maintains better heat I guess.. the power-vape could be dialed to a certain watt, but i don't trust it actually did it..because there wasn't much difference. with the VS, I can taste the actual difference as I try various volts, etc. its suggested 8 watts is ideal by charts etc.. but with the VS, I can try 9 watts ( 4.2 v / 2.0 ohm coil ) and the flavors are better, the vape is better, etc.
I was frustrated with the nautilus after a few days, taste wasn't great, limited amount of vapor, etc couldnt chain vape it... with the VS, I can chain it ( until it eventually gets the tank warm.. then I chill a bit ), the taste is better, and I get a lot more vapor.
