Ever I bought a Kent water purifier and made a blunder. I was using aquaguard nova which was going nicely. but because of the service problem we deceided to go for OR-O so bought Kent Pearl the latest model. But most unfortunately no one responded for 48 hours after buying the devil. After persuing their help line and approaching the show room people 2 unskilled boys came for installatin, who could not explaing clearly what they are doing. After one and half hour time they could fix the unit, but left out the tap adoptor. They could not explaing how to start the machine.
Therefore I storngly sufggest not buy the Kent. beware you are entering into a problematic world altogether.
