I have had nothing but problems with this product and it frequently malfunctions and ruins easy foods such as rice. When it’s not scorching food by not pressurizing, it refuses to open after the food is done for as long as an hour. There is also no safety release valve to manually address that problem.  When I contacted the company, I was told to clean it and it was user error and not a defective product, but I clean it every time and a quick google search will show you it’s a common issue
