The user interface has much built in so choices are very easy to make and get you up and using the oven quickly.  The fact that oven temps are already established for common recipes is very nice! My one disappointment so far is in the timer feature - not the cook timer but the general timer.  You can only set hours and minutes, not seconds; and, you cannot add time to a running timer.  For an appliance of this cost is seems a little ridiculous not to put in seconds (what if you want to set a 90 second timer) or add time to a running timer.  In the latter you have to cancel the timer and start over. This is particularly not useful if say you are baking cookies or pie and want to add a few minutes to the timer.
