I bought Marvello in 2005, after 3 yrs+ using the system, I dun feel much different like when i 1st use Alkaline water, so i purposely bring my water to test the antioxidant. Surprisingly, the antioxidant drop half of which stated there. for level 4, PH10, It suppose to give me ORP 400+ while I tested it about 190 only. After I do some reading, I guess, the antioxidant might be affected by the smaller surface area of platinum plate of Marvello system.
I change to use KYK 25000 from H2O, and I really experience the difference btw these 2 brands. Im very satisfied with KYK Machine. KYK is from Prof Dr KYK who has been in this industrial for more than 20 yrs, and still lecturing in uni and do a lot of research, so I have more confidence in his products.
As I understand, to be publish in SPH, if they claimed that they are No1, they must show the certificate/ proof to SPH, so I believe that KYK is No 1 in Korea, they can cheat the public, but not easy to cheat SPH.
