if you want high PH water just go to harvey norman and buy panasonic brand. This kangen water is more to bullshit pver price with same function as panasonic, my house got 1 unit and we replace it to pansonic after 3 years of using kangen.. after sales service is shitty and maintenance price is shitty. dont listen to the sales person bullshit that can kill cancer or what fark. just go for Panasonic brand

but if you manage to convince someone to install this bullshit, the sales person can split the commission with you. Our family already make money from it, so we switch to Panasonic for lower maintenance fees and less hassle.
