After a long market research, I poet for this steamer. - Simple programming - Warning about the lack of water - Keeps warm - Fitting for easy storage - 3 separate compartments for the cooking of different flavors Including: 2 compartments that keep water: convenient if necessary, the 3rd is a grid: convenient for sensitive waste non-organic fruits & vegetables! Some reviews say the battery compartment fits badly for cooking: it is what one can say really. But in reality, no steam comes out of the sides. It is therefore reliable! I use it every day for over a month RAS !!!! And baking my salmon steam has never been perfect ;-)
