So after a full day of vaping on the Zeta using a tobacco salts 'joose' I can say I am enjoying this as an option to my normal DL vapes. I'm satisfied by the flavor and airflow but the flavor is not way different than a few other MTL units I have. But, no leaking, good wicking with absolutely no dry hits and a pleasant, smooth vapor production for such a little unit. The small capacity is no issue for a MTL vape. Easy fill. Overall I am very pleased with the build quality. I am not using the ceramic deck insert so I have no comparison on with or without it. Worth the low $$ sale price I paid on it.
