I am writing this review as I have used this pressure cooker for 3 years almost everyday without a single issue. Litterally didnt even changed the ring. I really want to let everyone know that hawkins contura espevially 6.5 litres cooker is the best choice for every household who have to prepare indian food everyday wether in a small or huge quantity. This cooker size is enough. But As it is 6.5 litres so its bit heavy. As far as shape is concerned its base is quiet huge so food preparation and storage becomes very convinient. Also it looks very trendy in the kitchen. I just love its look. And it never looks old even after rough usage. Really really value for money.
