I love the stovetop and oven- both work great.  However the function buttons are difficult. There are two functions for some buttons so that you need to keep the manual Close buy.  Setting the clock is especially cumbersome- I had difficulty setting it the first time but eventually got it. After a power outage I could not get it to reset- using the directions in the manual.  Customer service could not talk me through it. They sent a tech to the house and after multiple trial and errors we discerned that it only works if you use a finger but not your thumb.
