Its a nice chip, but without the ability to swap out batteries can be a deal breaker for me... I would have to charge the dna 200 at least twice a day and leave it overnight to meet my vaping needs...
Until they come out with a swappable option (3x 18650).. I might have to opt for the cloudmaker sx mod or snow wolf... Jus my opinion tho...
I think you'll see at least a few options you can actually get your hands on by early fall and by winter likely a slew. It's still too new but several manufacturers have already said they are ramping up.
I'm in the same boat. I go through 3 18650s a day.
