Yeah, I have a couple Zenith's and I really love em overall, except that the airflow doesn't get as tight as on the Naut2S. But since I like a super tight airflow, I see a use for this. But if you like the airflow on the Zenith, I can't imagine a reason for getting this one. The topfill, coil change, flavor...pretty much everything else about the Zenith is superior.
