I received a good response and service from this Aqua Swach Water Purifiers, Nagasandra (Shivu. M ). I bought the Aquabuard RO + UV with a capacity of 12 litres from this dealer. They responded quickly and 2 technicians came to my house. They have installed within 2 hours and done the service perfectly. Now it's working fine. They have collected aroundRs.10,500 including installation charges, I don't know whether he charged me reasonable or not. I am satisfied with their service.
