2 months ago, I bought this product for about 1700 Rs, which was at that time among the most popular and cheap filter on Flipkart. It is a easy to fit purifier. A booklet is available to guide you step by step on how to fit and clear the filter. Being one of the cheapest purifier there are some important limittions to be noted - It is suggestible to buy this product only if you have drinking water connection(soft water or Manjeera water). Regular cleaning in 15 days is required. After 2 months usage, it is evident from the stains on the filter that the filter works well. But complete removal of such stains is not possible. The strong taste of the tap water after filtering surely has become milder. For a first time buyer of a water filter this has been a good experience on how the water filtering process work.
