  1. What is the best settings for using the zenith? I keep getting “check autimizer”. Changed the coil, and message goes. I’ve changed the coil 3 times. I have only had the vape for 3 days?

    • Hi Michael,

      Check atomizer means your tank is not making a connection with your mod. What mod are you using? The mod could be at fault, especially if you’ve replaced the coil and are still seeing the same message.

  2. What is the difference between the Kroma-A Zenith kit and the Kroma-A Zenith kit (UL Certified Version)? Were there any hardware, internal or firmware changes? I am curious since I just bought a Kroma-A Zenith kit last October and now it looks like there is a new model or revision but outside of the certification I do not see any differences listed.

  3. Hi!

    Quick question. I ordered one yesterday in my country. The Kroma kit. In the color black and white. But I can’t seem to find it on you’re website in this color.. Is that an older version? Am I missing out know (and I don’t mean just by color?!)

    Thanks for youre response in advance.

    • Hi Joost,

      There have been quite a few Kroma’s in the Kroma line over the years. The one you describe is likely the Kroma-A, which was bundled with the Axiom tank.

      The main difference between that Kroma-A and the one on this page is the bundled atomizer and the UL certification.

      Hope this helps!
