Product review (4 stars): Pleased with function and looks but have concerns
Installed to vent directly outside thru the wall, 4 inches from back of vent to outside air.  Not having to vent thru cabinet above is a huge plus if hung on outside wall.

Pros:  Even this smaller (290 cfm) unit throws out a LOT of air!  Glad we did not bother with the more powerful 400 cfm version but had to buy the less powerful one to avoid city code requirement for additional makeup air contraption in basement.  So far using on the lowest of 4 settings and happy with the quantity of air removed from house.  Looks great!  Lots of light but remember halogen bulbs throw heat so using the low setting to avoid that.

Cons:  Entire vent hoot arrives wrapped in tape to protect stainless surface-- but removing it is like taking off duct tape well burnished on!  Unexpectedly hard to remove, and since it was fabricated with the tape applied to all the surfaces before assembly we still can't get into the crevasses to remove the tapelike covering and the ragged remainders show to tall people.  Consider not tearing off the tape at seams and using a razor blade to cut it off cleaner.  I'm also concerned about winter drafts.  This is on a north facing wall and the flap provided with the vent hood doesn't seal off more than 60% of the opening when shut.  There is an outside piece (owner provided) that seals completely but it's thin and I'm worried about winter drafts.  May have to craft some kind of insert to seal the inside opening (where the air leaves the range hood) better.  Also, grills are very flimsy and easy to crease so definitely remove before installing.

Neither pro nor con:  noise is average in volume, but definitely not "noisy"
