I'd like to report some issues that I've found with this RTA, although I still love it:
1) If it is left at any sort of an angle other than completely vertical for any extended period (1 hour+), it will leak. It's happened twice now (I have an Orchid and know how to wick these tanks, I've even plugged the channels completely and it still occurs). I just came back to the entire 4.5mL in a pool in my vape bag. Grrrr...
2) When filling, I love the filing hole system but it should not be located so close to the juice channels. When the pressure begins building from filling, without fail, a waterfall of juice comes shooting out of the drip tip. I can't get this tank more than ¾ full because any further than that and it will come pouring out, even with the channels completely plugged with wick.
Other than those two things, I have it build at 0.4Ω at 22.5W on my DNA30 and the vape is absolutely incredible.
