I am using this for the last 3 years . No problem. But water taste is not good during our stay in different residences in three areas of chennai, Perungalthur to MRC nagar( RA puram) and now in Tiruneermalai near chromopet. One year in each location.
Other products of neighbours in all three areas listed above are having better taste.
The other problem is we can hold one liter bottle or large vessel to get water from the unit due to the bottom tray which can not be removed. If the company makes the bottom tray removable instead of fixed moulded bottom tray, it will be very usefull for homes.
Overall We are not happy with this buy!
