Got my HM dna 40 today and got it all set up. Threw on a magma with a .16 ohm build and it's vaping great. I am amazed at the temp protection and how easy and worry free it makes things. Did about 11 wraps ni200 28ga. I find myself vaping at a lower wattage. The magma is also a great RDA Im still finding my sweet spot between 1-2mm air hole single coil mode! If this won't keep me away from analogs. I don't think anything will!
