I have been using the prestige pressure cooker for almost 5 years now and I am very much happy with the cooker. It is really of good quality and brand that you can trust. I bought this pressure cooker from a local prestige cooker seller and he gave me warranty of 5 years on this product and a list of all the repair shop for the spare parts which was really convenient.
But fortunately to sync the I didn't had to use that repair book due to the reason that the pressure cooker turned out to be a really durable product. We have been using 2 pressure cooker of prestige, one for veg and one for non veg and the food that it cooks is really fast and saves fuel and is very much efficient.
I have been cooking rice, dal and many other things like borland from the last 5 years and I didn't had any major problems apart from the minor fixes that are never and were not a bug deal.
The cooker is ISI approved so you don't have to worry about the safety of the product also. It is very efficient and durable and I am really happy with the product.
