Installed ourselves in less than 30 minutes.  

This model has 400 CFMs.  That is about 33% mose than most other over-the-range microwaves.  It is loud on high but it has a medium and low setting.  It's nice to be able to put it on high when needed.  You can change the fan direction before installing to have it recirculate, vent up or vent back.  It is very easy to change this.  If you chose to have the air blow back into your kitchen, it contains a second filter to remove oils and odors.  

After you have this microwave installed, make sure that it is not on demo mode before using.  The demo mode runs your selection for a couple of seconds and stops.  

You can turn off the clock display, and set the turntable to not rotate.

Lights that illuminate your stovetop are very bright.  I like this.
