Rose gold colour is gorgeous. This is a direct-to-lung device: air hole is fixed. Be careful with the tank: it's press fitted on the deck (which is screwed on the battery), so pulling it could lead to catastrophic results.

Let's be clear about that rba: the idea is great. What is lacking is the machining and the engineering: first of all, the positive pin isn't threaded and screwed on the positive post, which is quite odd - to say the least. It's just "touching" the post, which works quite good until the deck is fitted into the atty's base, but as soon as you unscrew it, it can possibly fall apart. Upon the first build, I was continously getting the "atomizer short" message. I figured out that the lower part of the chimney's cap was touching the posts when screwed in. I had to file down the corners of both posts at an angle, and reducing the base of the chimney's cap a millimeter too. Now it's working quite good to speak the truth. Still, I can't get why the central positive pin isn't threaded to the positive post.

Those coils are exceptional: I rebuilt vertically an eleaf ECR head, mounted on a I-just S clone, and it's quite a rocket!!!

Not bad. I think I'll be cutting a couple of millimiters out from the drip tip, to make it even shorter. The upper part was blocking the drip tip due to an excess of paint in the inner side - I managed to sand it and it worked just great. I was actually expecting the bottom feeder pin... I'll see if I can manage to drill the original with a 1mm drill bit.

This is quite a good bottom feeder mod. Bottle capaticy is ok. Spare bottle to carry some more liquid around. Nice design, reminds a bit of the Reuleaux. Seems to drain batteries quite quickly though...
