We've had our new microwave for almost 30 days and have appreciated several features, such as one button operation for 1,2, or 3 minutes, switchable turntable, and +30 sec., that were not available on our previous unit.  Installation was straight forward with the exception of needing to drill a third hole for the additional supporting bolt this model offers.
One small area where an improvment might be appreciated is to emboss the touchplate over the light switch,  It often takes me several pokes to switch it on in a totally dark room.
