Product review (1 stars): Never worked
We have had this over for about 4 years. As soon as we installed it there was a problem. The clock was loosing time. A few minutes a day. By the end of the week it was off by 20 min. Bosch sent a replacement part. The new part had the same problem so it had to be replaced again.

The warm setting never reached the set temp.  (about 170 F). It could be left on for 1 hour and it would still be preheating. Bosch replace the entire circuit board or motherboard. It still has the same problem.

One of their repair men damaged our blower which we discovered because one side of the oven would not cook food. Cookies on one side were baked, the other side was still uncooked. Another service call. The repair man wanted me to test this on every setting take notes and tell him when it happened and then call him back. If I am going to do a masters thesis it is not going to involve ovens. I did not do this. Bosch sent out another repair man. The oven cooks more evenly but food on the left is still less done than the right.

Error messages are common. Customer service tells you to turn the circuit breaker off and on. This works but is frustrating, especially when the oven is brand new. Every repair is two days off of work. One to diagnose the problem and order the parts, another to repair it.

A thermostat of some sort blew so the top oven stopped working. This was just past the one year warranty mark so we had to pay to have it fixed. We still get occasional error messages and the warm setting never preheats. I will never buy another bosch appliance.
