The main reason I've held back from buying any DNA 200 box mod was because I became intimidated by the Escribe software, and heard there were problems with many models initially. This model is perfected now. If you don't have Windows, the firmware is more than satisfactory with decent battery life. I love to set my 3-cell lipo battery pack at it's intended 1300 mAh or whatever the software rounds down to slightly. 11.1 nominal volts, and up to 50a continuous current (55a instant pulse for a few seconds)...this is why I made the decision to jump aboard the DNA 200 wagon. I'm sick of batteries, tearing wraps from constant use, and none are worth using except VTC4s, so I needed this mod exactly now in my life. I'm running a new .2ohm clapton coil in my Aspire Cleito subohm tank up to 70W. beginners can adjust the settings in the software that make sense to them, if the options are not clear to you, don't touch them. I still have a lot to learn about the most detailed customization features. Make sure you don't use too strong/fast of a charger BTW. It can break your board. It vapes like a dream, feels nice in the hand, and is easy to use right out of the box.
