I had searched a lot of RO systems. Kent us the choice for me. A known person of mine introduced me to a manufacturer who assembles the RO system of its own brand. Kent Ro was costing me around Rs 14000 and that local brand RO is costing me around Rs 5500.
I asked the reason for this, he said the components we are using are of best quality and you can get the quality of RO checked by any third party. I purchased that RO and it is working perfectly fine from last 4 years
