Our family bought this product before a month ago but the kent services was very bad and u don't believe that they take more than 7 days. I don't know that u all know this fact that RO is banned in whole world like USA, UK, CANADA, etc. Because RO purifier kill all the mineral of the water which makes us healthy but it kill all the minerals. That is not good for health. I u don't believe than search it on google. The seller who come to ur house and give u a practical test. They all are fake. So be carefull before buy any type of RO
