I have been using it for the past one year and never had any problems with it.I bought from a nearby electronics store as the salesman suggested me by showing me a demo.
In my area the water that we receive is some times harsh or muddy and that’s the only reason compelled me to buy this.I am not disappointed with it.
There are many models of this purifier available I bought the 30-DS as suggested by the sales person for purifying muddy water issues.One can even go for some advanced versions as well according to their requirement.I am definitely recommending this product .
