Aspire has already announced they will be offering Ni200 heads for DNA40 devices. I would expect Kanger will not be far behind.
I did a Kanger Protank rebuild using Ni200 as a practice run for using a Sophia with my Vapor Flask (loaned my Sophia to a friend and have not gotten it back yet). I started with 30g and quickly found I needed to go to 32g to get anything workable. 34g was better yet – the cup size on the Protank head doesn’t give you much room to work. Wicked it with cotton and the vape was so good that I’m building more. Getting flavors out of it that are unreal. Finding that 420 degrees is a good spot for most of my fruit juices; 400 degrees for candy flavors.
