I purchased a home that had the Bosch appliance already installed.  So, I didnt buy them nor researched them - I just got them.  Well, I am extremely pleased.  I laughed when I saw the smart feature because I thought to myself - who would ever use it....well, I do.  I love being able to get on with activity around the house and be notified the oven is pre-heated - or to be outside and the alarm on the phone goes off when the timer is done.  Finally, the cook time on a package is the shortest time on the appliance.  Love this setup.
