I received mine yesterday, and have since put a few different builds in it, experimenting with coil position.
Initial impression is that this is a well machined, and well presented RTA. It arrived clean and well packed. I smelled a hint of machine oil, so I gave it a light scrub with soap and water. Threading and finish is excellent. I have not had any trouble with the posts clipping wires.
The reason it's been through 3 builds at this point, is that it took me 3 trys to realize where to position the coils to get them in front of an air hole. Centered on the deck does not work. They should be off to the side towards a negative post, but it's important to figure out which negative post they should be near on each side. I had to screw the deck in, then mark the bottom of the base with sharpie marker where each air hole lined up. I then rebuilt it and positioned the coils accordingly. The coils also need to be fairly high, and I've considered just securing them around the screws Fogger style to shorten the lead length. First two builds were terrible with harsh hits because of indirect airflow to the coil.
This is definitely a lung hitters tank. It has huge RDA style air flow. Air flow can be adjusted down for MTL, but here's my gripe: I don't see the point of the air holes that do not center on a coil. The two air holes that do not face a coil lead directly to a negative post. Maybe it's just to make the tank more airy, but for MTL, they are unnecessary, and IMO, kill flavor. It would have been neat for them to include a vape band that only had two holes in it. I'm going to have my wife bring a few vape bands home from work and I will experiment with making my own.
This thing wicks like beast, and is pretty hard to screw up in that regard. Just tuck the tails under the coil. Flavor is decent but I'll reserve final judgement on it till I've had a chance to tune it to my preference a bit.
Current build is 26ga Kanthal, 8 wrap contact coils, at 2.4mm. Now that I have the coil position sorted, I will likely go back to spaced coils on the next build.
