I was really excited about this thing when I first saw it. A great postless build deck with properly aligned wick channels, and that wonderfully smooth honeycomb style airflow in a sub-30mm tank. The Supreme V2 is close to this, but the postless deck available for it is the old style one developed for the original Supreme, with misaligned wick channels, rather than the great one that came with the Plus. Anyway, I was pretty excited until I watched some reviews. It seems that Geekvape wanted to simplify this style of tank, maybe to have less parts to lose, maybe because they just like it this way, who knows, but they did it and it sucks,
To that end, the entire bottom end is press fit together. The deck is press fit to the base, and the AFC ring is trapped between two pieces press fit together. This may be an opinion that's not shared by many, but I don't like press fit parts. They tend to loosen/fail over time, which can lead to leaking, they prevent you from accessing and changing O-rings contained within, and sometimes they're loose and/or defective right from the factory. The fact that the AFC ring isn't removable means that you obviously can't clean under it, and juice WILL work its way in there and get on your fingers when you adjust it, and just generally be a nuisance.
Also, the fact that the top section(where the top cap screws into) is totally flat will create another annoyingly messy problem. When you screw the cap down, juice is going to be squeezed out by the flat top cap pressing down onto the flat top section of the tank. Even if you are extremely careful and every drop of juice goes perfectly in the hole, once you close it and open it again there will be juice there waiting to squeeze out when you tighten it back down. This means you either have to wipe down the top section of the tank, and the underside of the top cap every time you fill, or wipe juice from around the top cap when you screw it down.
Between the non-removable AFC ring collecting and seeping juice, and the flat top section/top cap squeezing it out every time you fill, you have an annoyingly messy tank. Probably pretty flavorful, definitely easy to build and wick, but you won't be able to keep the juice on the INSIDE, and that'll likely only get worse as the press fitting loosens and/or the inaccessible O-rings within the press fit parts wear out.
Sorry to rant. I don't know why Geekvape's thoughtless, bumbling, ignorant job on this tank irked me so bad, but it did. I feel much better now though!
