Material is not good at all. It a totally waste product they delivered. After purchase, during this first rainy season white fungus coming out. Even after cleaning also its not stopping there, due to the moisture in air after two three days it's again coming out.
Its not a very good product. Its may be okay at 4000 price but it needs a lot maintenance. Specially in rainy season lot of white fungus appear youll get tired cleaning it everyday. It attaracts lot of dust.
