Product review (4 stars): We used the rectangular top exhaust fitting and overall this unit works pretty well at removing cooking fumes from our gas range
After a lot of research we narrowed down our results to either this unit or a chinese brand Pacific range hood that my parents own. We chose this unit as it was the cheaper option.

We replaced our microwave/exhaust with this Kobe unit. We used the rectangular top exhaust fitting and overall this unit works pretty well at removing cooking fumes from our gas range at speed setting 5. Even at the top speed setting the unit isn't that loud, with that being said its still not that quiet on the lowest setting either.

The installation process for this unit was a pain, with a lack of clear instructions (very user unfriendly manual). Please note *that in order to install this unit we ended up using the car jack from the wife's car and a bunch of text books set on top of our stove to lift/jack the unit up under the cabinets so I could DRILL HOLES THROUGH THE RANGE HOOD (why did you design it this way!) and mount it under neath the cabinet.
