They have nailed it in fooling their customers. They say its a water purifier which does not use electricity and hence saves your money. But they didnt tell you that you have to pay 3000 every 15-20 days moreover the assembly is of poor quality. It starts leaking over a period of time. You have to take efforts to clean it from time to time. If you have borewell water at your place then you will have to change the filters every two weeks or it would stop working completely. I would not recommend this to anyone
