Kent Ro company is very popular now a days we have seen many advertisement on newspaper and television of this RO in the advertisement they say that this RO is very best in quality but really it is not so that much is explained in the advertisement this RO is fails to provides a sufficient amount of TDS if the amount of TDS is less then also it can harmful and if the amount of TDS is high then also it is harmful to us it may cause headdak or hair fall. Water purified by this RO is not so good as we want. Design of this RO is worst design is very old type style and it cannot able to give a batter look. Durability of this RO is very less because it want service very shortly and its services are very costly and other parts of this RO are costly. It consume more electricity and affect our pocket it produces more salty water and gives very less water for drinking. Services of this company not so good ant cannot satisfy the customers.
