Query: You were warned.

The chrome on the racks in this oven chips off very quickly into your food. Virtually no one carries replacement parts. The oven cooks OK, but the numbers that tell you temperature and time wash off with dish soap. So after a few uses, you have to guess. Aroma's customer service is answered by a machine - even in the middle of the day - and you are told to call back during regular business hours. If you do elect to leave message - you will grow old waiting for a return call.
