It is easy to use.  I am loving the European convection.  Super crispy pizza crust and chicken skin.  Water boils way faster than gas or electric speed burners.  It also can be adjusted way down to a bare simmer.  I'm an experienced cook and this has definitely upped my game!  This replaced a wall oven and cooktop. My only complaint is the storage drawer is a little hard to open and close and seems a bit flimsy.
