I have been following the DNA200 forum on ECF and finally became curious of the Hana issues and read the whole thread. I have a real early release. I bought it on the day it came out. Checked my e-mail, July 26,2015. At first the power button seemed a little wonky. I would push it but sometimes it would not fire. It seemed kind of crunchy. I would have to push a little harder to get past it. I figured it was just some dust because it works fine now. I do not have another TC device to compare resistance to but on kanthal builds there is a 0.01 difference usually. Comparing what builds are supposed to be through steam engine and what shows up on screen and through Escribe are pretty accurate. But going back to my original point, considering the original crunchiness, should I be worried something came lose when it freed up? Thanks. RickT
