The Zeus X is a substantial improvement over previous Zeus models. The deck is roomier and features a detachable internal airflow chamber shroud that slots in to protect the wicking material as the tank is screwed on. The post holes are 9mm apart measured at the outer edges, 6mm at the inner edges. There is sufficient clearance to fit a pair of ⌀3.5 coils. It can run a 0.12Ω build at 100W before overheating becomes an issue. Compared to previous models, the juice channels are wider for better flow and reduced need to rake the cotton. The coils are secured by slot-drive screws, and hex screws are also included as an alternative. There is access to trim the legs with a sufficiently small pair of diagonal pliers. It comes with the standard Geekvape accessory bag full of every type of O-ring imaginable, spare screws and drivers, ultem drip tip, drip tip adapter, straight glass and bubble glass. It also includes a quality pair of nichrome fused clapton 0.4ohm coils and a pair of fancy shoelace wicks so you're ready to do your first build out of the box. The installed low-profile drip tip is the shortest I've ever seen and the Ultem one looks great. This is indeed a no-leak tank as long as the cotton is installed properly. Even when lying on its side. Even if you place it upside down! Be sure that the cotton fills the wicking channels all the way down to the bottom. I don't need to rake my cotton at all. The cotton forms the plug that regulates juice flow from the tank so it must completely fill that space to prevent spitting and flooding. This RTA is spectacular—my instant favorite.
