I have the protovapor xpv and I love it. A few minor issues with the button, but protovapor has the best customer service of any company i have ever dealt with even outside of
vaping.
Chins is making some DNA30 clones now that are like 100 bucks….I have no clue but if i had to put money its definitely not an authentic DNA30 chip. Good reviews though.
Go to JCMSvapes.com? I think thats right ill double check and post back if its wrong. This dude makes really really nice dna30 devices for like 150-200 dollars and one has a 2400mah li-po battery and another a 5400mah li-po….like that ish is no joke. There is a catch for it though, he only does a limited amount per month and they sell out super quick, subscribe to the website and it will let you know certain times. Hope that helps!!
