I had purchased a Hindware 3 burner cook top model Optra GL(A1) iin Nov 2012. Since then there have been problems on a regular basis however they were resolved albeit with some delays. On 26 May 2012 there was a fire in one of the burner for which a complain was registered with the call centre on 27 May 2014. Since there has been response from the company or any feed back despite repeated calls to the call centre and the dealer. Very poor service that totally frustrates! Avoid these products as while selling they make big promises but after sales service and customer support is really pathetic!
