I purchased it from online shopping websites but it has turned to giving trouble to me. Initially it was running well without any problem but after a few days I noticed that continuously around 24 hours a day water is flowing out through the RO then I called the service center and they just replaced with cheapest parts as possible and suddenly a loud noise started coming from it after few days of repairing. Don’t buy it. Till now nothing has been solved and atlast I have to purchase a new Ro.
