Therefor the 2018 (non Premium Edition) model is without any doubt a perfect comparing point between any newer models when being tested. In this video the test reveals and confirms the same exact levels measured by the chromatography machine therefore showing that this testing method is very accurate way to measure ml per minute accurately. When compared with the Premium Edition it is very obvious that the Premium Edition model makes much higher levels of hydrogen than the Non Premium Edition model using the exact same method during live testing. The test shows that the Non Premium Edition model makes at least what it claims which is at least 26ml of hydrogen per minutes and the 2019 Premium Edition shows to make at least 120ml per minute with the exact same test performed and testing method.
