Prestige pressure cooker we are using from years.first of all brand prestige is very good for cooker.it comes in all sizes according to your family member.we have both big and small.but we mostly use big one because we have a joint and big family.it gives perfect boiling of rice, sabzis, the thing that you must know only is perfect timing for the dish you making.it makes proper whistle, even I am room I can hear it, I dont have to wait in kitchen for listening it.its easy to use and cooking is done fast with the help of it.it is long lasting definately, we are using it from 3 , 4 years and it is working good.style and design is also good.cleaning method is that if you cook smething just leave under water for 10 minutes then clean it with soap.food doesnt stick to the cooker interior which is best part.service maintaince is very rare like once in a blue moon.
