This is the Reckoning RDA which I have to say I'm still struggling with coil placement and it drives me crazy that the little Center clamp is always off-kilter. I also see it's got a little bit of uneven color. It's ohms are stable and perfectly fine. Does anyone have a suggestion on how to better place coils. I start with the outer clamps to try to hold it in position and then I do the inner one but it's really hard to screw down the clamp that they both share that is angled and keep the leg in place.
