This definitely is a great product and the name of TATA adds a lot of values to it, because its a brand well trusted in India. And I tried to explore, they have a pretty good dealer network across India ( 1000). And another good thing is that they are having collaboration with the Government and providing subsidies as well. So that will boost the usage of such great products, thus reducing the normal electricity consumption , which would in turn result in less electricity charges for others.
