The Zeus that I received (gunmetal) has some discoloration in the top cap. One side is noticeably darker than the other. Out of the box I had a hard time taking it apart since the top was screwed down too hard or cross threaded I had to use pliers to disassemble it. I put a build in it and used it a bit before taking it apart but because it wasn't assembled properly I got a lot of dry hits on it. The claim of this thing being leak proof is absolutely true in my experience even turning it upside down or on it's side for a long period of time it didn't leak. With the AFC half opened I get a nice saturated, flavorful semi-restricted lung hit that's still nice and warm at 50W despite being a bit taller than many of the 2ml tanks I use. Using this RTA reminded me how I love simple single coil builds and despite the finish flaws it looks fantastic on my Aegis.
