Hi all, i am a newbie here. Thinking of want to buy ionizer system. But there are too many brands in the market, for like panasonic, alkalife , AO,  Kangen also. My friend has bought kangen but it cost RM12,000. I came across ioniser from Bacfree and it cost around RM9500++. May i know which is better? and Have you all heard about the ioniser system from Bacfree? They claimed that the product are from Hitachi, and have self cleaning system and can do whatever function that Kangen water can do also.

Please help.
