I purchased few non stick pans make NIRLAP from BigBazaar, Guwahati. But within three months of purchase one of them is damaged. Though I have not used other pan for much. But I hope the other one will also be the same after few use. The company claim for 1 yr warranty. I do not know the product are of low quality or the BigBazaar is doing the fake thing. Hope some one will reply.
