Whoa, Pardes, so glad you are okay. What a story! With my kitchen renovation in full swing, I'm sans smoke detectors at the moment. Thanks for the link to the reviews. I'll get some this week. My new micro is not a spacemaker, and the old one I'm using during the renovations is only plugged in when in use.

What was burning--the walls?

It's also important to have a fire extinguisher in the kitchen and easily accessible.
