Worst pressure cooker I ever  bought. Bottom does not tolerate high heat, food burns to bottom which is too thin. I had to give it away since I had to throw out burnt food three times. I will never buy this item again. I would actually like to get a refund, since it cost me a lot of time to clean the burnt bottom and money to replace the burnt food. When recipe asks for 2 cups of water, you actually need 4 cups to avoid burning of bottom.
