Product review (5 stars): Wow,  powerful and quiet.
Wow.  The quality is amazing. Installation is not for the newbie. Takes some planning, the right tools,  and a second pair of hands. Take your time.  At max speed it's not loud. Our install replaced an over the stove microwave oven that was just too high to feel safe. The original duct work needed to be corrected as a result of a shoddy install. Took most of the day, trying not to rush things. Love the look.  We now have a counter top microwave; love the result. Highly recommend.
