My aunt recommended this product last year, quite a good performance, no extreme services were required as for now. Sometimes water taste changes.
But soon after cleaning it again it becomes regular and good for drink. Had word with the service guy, Neeraj who came and solved our problems in blink of minutes. In past have came across few brands in water filtering. but trust me, the services what Zero B is giving us as for now, is really great. I hope they continue this practice.
