We have purchased water purifier and it is worst.It has a nice look and it is good purifing but when the machine is starting it is making sounds for 25 to 30 times. we asked for exchange they said there is no stock and we have called them 2 months daily after 2 months they gave us exchange. the new one also making sounds and TDS is more then 30. and the service is good they are responding good but the company has to rectify these errors and bugs. waste of buying this product.
