Hello friends, I bought Kent RO 2 years ago . performance was top for atleast six month. after this membrane speed of filter gets decreases and quality is also low. water is very polluted everywhere so it is necessary to buy filters. It is easy to use and simple working step. Easy to clean the body. Its compact design is stylish and looking great. Service and support are not good by team. It is worked for not long time we have to service after certain period.
