I have total 3 prestige cookers of different size capacity. It’s one of the best cooker company. At my home, it’s been used since many years and I don’t recall a single complaint has logged by us. They are easy to use n very durable. No leak has been noticed so far. I will not comment on services n support as the cooker has never given me any opportunity to call them n test them. It’s a must buy cooker in the long run. As it’s highly durable. The ring also works well for many many years. It’s easy in cleaning. Thanks
