The Flavour and vapour production with a DNA 30 is just as good as any Mec at .6 and above
I use Mecs and DNA's I don't go lower than .6 I really like the DNA's
With a Mec it comes out of the gate really good but then looses steam as the battery goes down
Once the battery is down in the Mec you need to take it out and charge it with a DNA you can just hook it up usb on your PC home plug or even in the car and keep on going while the battery charges
The DNA 30 gives a consistent hit all the way down You really can't beat that
I made 3 DNA 30 mods to date and have another DNA 30 chip
I just ordered an empty box from FT it comes with every thing but the Chip and charging port for 20 bucks
Add a real dna 30 for another 49.99and charging port for 7 bucks and you got a great deal on a nice box mod
I will use my own 510(Fat Daddy 510) cause there's isn't really up to snuff
For less than the Hana Clone you can have home made box mod with a real DNA 30 chip that looks just like a real Hana V3
If you have a little soldering skills you really can't go wrong going this route IMO
