Free Demo for a water purifier made me feel at ease. I had to actually hunt for weeks to get the information that I needed. We had to be extra careful regarding drinking water as there are small kids at home. I liked the latest technology of Zero B Eco RO.
My family finalized to install it after the free demo. Customer care was good to revert back as and when needed along with the solution. We are using it since 14 months and it is really good.
