I was looking for a MW with good light and ventilation.  Twin LED lights illuminate the entire cook top. The slide out front shelf catches cooking vapors and smoke. The  two return vents at rage rear angle to catch the vapors. " Thanks to the extended vent, the microwave capture rate is double the rate of typical over-the-range models."    4 speed fan has good 
volume when the shelf is extended. I like the knob dial to set cook time, timer and such.
