This teleshopping is available through missed call to this company. But I have seen the bitter experience of my colleague. He bought a smart phone with gorilla glass from Naptol.
Unfortunately, after he bought in two days his mobile display was failed. Because of lack of gurantee, he complained to consumer forum. Still now, there is no reply on behalf of this company. Here at low prices products are available but we could not judge about the reliability of the product.
