Screews loosen up after two months of use. It is the worst pressure cooker made by Pretige .I have been using this product for six months. In the beginning, it seems to be worth buying but after some days its handle screws starts getting loose and the handle came out, so I suggest you guys not to buy this product. I bought prestige cook top 6.0 . After a month, the coil in that stove got damaged and went to Big bazar for changing it. But they said I have to contact service centre which is located 5 km apart. When I went there, they asked me to file an online complaint. So, I returned back and filed a complaint. Its been four months now, and till now there is no response. They have to see to the customers and make proper response not only for buying your bloody products .
