Got mine a couple days ago from MVS. Here's my quick review.
Pros:
1) Great looking tank. Definitely the best looking I've owned. (I got the black one).
2) Three drip tips provided to suit most people's style.
3) Included are a boat load of different colored o-rings, screws, a screwdriver, and a couple of nice fat braided coils.
4) Not the easiest deck to build but nowhere as difficult as older tanks (prior to this I hadn't bought an RTA in about 2 years). Overall I would call the build experience good. Wicking is very easy too, despite the "staggered" wicking channels.
5) Haven't seen a leak and I've run a bunch of tanks of juice through this already.
6) Perhaps the best top fill system I've personally owned next to OBS's side fill (which many have copied).
7) Low profile and not as tall as the older 22mm tanks I've been using. I prefer short tanks -- they just look better.
8) Mine came whistle clean and in mint condition. I saw a guy earlier who said his came with gunk all over it. I suspect he either bought a counterfeit or someone in between Geek Vape and his retailer opened the box. (If it came from Fasttech, well, that might explain it). I have zero issues with the package, presentation, or cleanliness of the tank. A+.
9) Single coil is a plus, especially if it can produce comparable vapor to smaller dual coil RTA's. I would rather have one big and fat coil than two smaller ones. Same amount of vapor for less work.
10) Price. $29.99 from American retailers (probably cheaper on FT). I remember when tanks of this machining quality would be $100 easily. Prices have dropped, which is good for us all. Chinese slave labor for the win.
11) Smooth airflow. Not very loud and doesn't whistle.
12) You can vape it to the last drop without much of a drop in quality. (I do vape temp control, just FYI).
13) Does temp control coild well. I am rocking a 24 gauge (3.5mm ID) titanium grade 1 wire right now. My 7 wrap coil "Ohmed out" to almost exactly what steam-engine says it should. No issues whatsoever with ohm fluctuations or instability.
Cons:
1) Getting the little etched Zeus head (on the bell) to line up unimpeded is hard. I have learned there are two possible positions the head will end up when you screw on the deck -- either covered up by the cage or perfectly aligned and not covered by the cage. Which setting you end up with in totally random each time. Sadly, the only way to get it right is trial and error. If you find that the Zeus head is covered, take your deck out and align the posts the exact opposite way and then screw it back down. This is going to drive OCD people nuts, I just know it.
2) The cage sometimes sticks to the deck when I disassemble the tank. Other tanks (like the Pharoah) include a locking mechanism to fix this. The Zeus has no such mechanism. This has caused more than one tank full of juice to spill when I took the deck off to work on my build.
3) The instruction manual says nothing about which o-rings go where. If you take them all out to clean them, you better remember where they all go (good luck). Some are obvious, but some aren't.
4) 25mm tanks will not fit on many devices without overhang. While I love the short stubby look of the tank, this sucks for people who have older devices (and some new ones). My daily driver is the VooPoo Drag (best chip not made by Evolv) and it can only accommodate 23mm without overhang. While not horrible, the Zeus looks kinda funky on the Drag. (This is not really a con, it's more of an observation).
5) Flavor. Not that impressed. Again, I am coming from older 22mm RTA's which have smaller chambers and more "compacted" airflow inside. Flavor is always going to be a function of the chamber (bell), it's size and shape. Smaller is better. Less airflow is better. The Zeus, being 25mm with a big deck and wide bore bell, is going to automatically have less flavor than an older 22mm direct lung tank and MUCH LESS flavor than a tootle puffing RTA. Cloud chucking has taken over the vaping world (and I am not even a MTL guy). It is what it is, as they say.
6) Don't care for the massive bore drip-tips and I don't see what people get out of them. They are exceedingly uncomfortable. Fortunately this is easily fixable with your own tip, so this is more of a gripe than a con.
7) I think the "3D" cheese grate airflow is a gimmick and probably it's only use is to mute the flavor. They probably would have done better just to omit that all together.
8) Adjusting the airflow ring can result in the top fill portion completely unscrewing and falling off if you're not careful. There's not enough room to put your fingers, especially if you have large (or fat) hands. (I have skinny fingers and even I had trouble unless I take the time to really look at it when I'm adjusting. I don't want to look at it, I just want to adjust and go).
9) I took the silicone gasket off the top cap to rinse and it was almost impossible to get it to sit flush back in the top cap. Took me about 15 mins of fiddling to even get it half way in. I've owned other tanks with the exact same silicone gasket and none of them had this problem.
10) It's a guzzler. I chain vape and using the included coil, I vaped a whole 4mL tank in about 10 minutes. This is not really the tank's fault, but is more of a function of the cloud chucking coils everyone uses these days.
11) Nowhere in the packaging did it specify what material the included coils are made of. PBusardo always gripes about this and I am with him 100%. The coils are almost certainly Kanthal or Nichrome, but it would still be nice to know for sure.
Would I recommend? If you're a cloud chucker, yes. If you're a flavor chaser, no.
