Product review (5 stars): Good product at reasonable price
Overall good product and works well, sound levels are reasonably good at peak speed have no complains.
Pros: 1. Works good for 870 cfm but quiet  2. Well built heavy gauge  3. Reasonable price (it was $289 for me)
Cons: 1. Touch screen panel button is something needs improvements very hard to press  2. Clock setting could be made simpler

Other points to consider:
a. Its heavy for 1 person to make a fit alone... it took a little bit extra effort to fix it well under my cabinet.
b. The vent outlet should have been 6 inch diameter (than 8 inch) - something that may be tough for some folks that have small space under the cabinet to fit the reducer/elbow (if your fix wanted it). I could work it out with some adjustments but was really the toughest part for us.

Over all I still give it a 5 start as it really worked for me after a fix and satisfied my need.
