First of the alarm is really quite quiet, goes for about 6 beeps and stops. Could be really easy to miss and there is no way to change it. Left me feeling disappointed in buying this model.
Cooking with it is lovely, fast heat up and then fan oven for the minimal time, food has came out perfect. Just that alarm is why it does not get 5 stars, I even contacted Bosch and they said no way to change it and was not interested in helping any more. I had been without an oven for 5 days, did not want the hassle of sending it back.
So great oven if you have really great hearing.
