I purchased Aquasure Nano Ro in Big bazar based on one of their customer care representatives, When I had to install it, the installation person promised to come, after waiting for 2 weeks and no one coming, I got a local plumber to install it for me, when the Euraka forbes people called me, I gave them a piece of my mind.
Cleaning aquasure nano ro is difficult as it is not transparent, also spare parts are not easily available and takes 2 months to reach, avoid aqua nano and go for other brands but make sure that you can see the inside and that it’s easy to clean.
