This rda was sent to me as a sample to try out and review. It has not been released yet, but is worth watching out for. It is all 304 Food-Grade Stainless Steel. Delrin insert where the drip tip fits in. Gorgeous and machining is Excellent. It has a brushed finish. Heat fins are in the middle to help keep heat transfer to your mod at a minimum. Which works very well. Air intake hole is in the center of the deck and let's out on the 2 sides on the bottom. Air flow is controlled by AFC ring. Big holes for you Cloud-chasers. I adjusted mine to a tighter draw, which I prefer. Love having the option. The deck has a Deep juice well. This can be set up as a single or double coil. There are 2 Positive and 2 Negative posts. The center post is adjustable. I set it up with single micro-coil using cotton wick. Vapor was very Tasty and dense. It comes with a spare-parts bag which includes an in bleached cotton pad. I really liked this rda and think it will be a hit with fellow vapers. Just love the workmanship and innovation that Focusecig is producing!
