I totally agree with JohnnyDaJackal's observations! If Zaino CS allows a carnauba user to lock in the carnauba looks they prefer (ex. Souveran, P21S) and increase the durability by several months (1-2 to 3-4 as an example) I think this is an absolute breakthrough product. The ZAIO also sounds like it will be nice for those who do not want to use ZFX or for those looking for a quick one step product. I look forward to hearing more reviews and trying them.
