Aquaguard salesman is one of those people u should never let inside your house. Beware of their sweet (but poisonous ) explanations about their products.
Just shut the door on their face. If u let these venomous snakes talk to u, they will make u buy their product. But once u buy the product, u will realize what kind of cheaters are they to what those salesmen told me.
I have suffered a lot because of buying this product. I dont want my fellow men in this country to suffer like this.
I advise u not to go for this product.
