Product review (4 stars): We really like the high CFM and the larger ducting size (8") ...
We took a chance on this range hood after reading reviews here and at Home Depot.  We really like the high CFM and the larger ducting size  (8") because we are getting ready to buy a gas range and want to be able to move air.

After turning it on the first few times, we happened to notice one of the plastic damper halves on the roof! Seems the plastic hinge pin got weakened or broken during installation (see photo). We contacted Cosmo, and they are sending a replacement.

We also like the rounded corners to minimize head scrapes. We installed it 37" above our range for the same reason.
We replaced the blue-ish LED Lights wtih brighter white LEDs and are pleased.

As other reviewers noted, the instruction manual isn't very clear, so we had to rely on comments from other reviewers and a neighbor who had some experience.
