My Mil has one . It does give you the perfect med rare steak . However I prefer the smells etc while cooking , this goes away with this method. It's smelled and silent. I also like caramelization of the fats etc. that goes away as well. Secondly lots of chemicals in the plastics are released with the heat. If you were going to cook something in a sauce it works real well. I did shrimp curry that was world class. Neat idea but not something I will buy. I think it works better in a commercial kitchen not a home kitchen. Find someone who has a set up and try it before you buy.
