Product review (1 stars): Stay clear of KAZE
Warning-This fan was in the orgional package, but was used. The blue packing protective film would not come off easily (because it was baked on). Once removed, found many dents and grease inside the unit. Contractor says the unit looks a couple of years old. Not sure how this happens. My best advise. Stay clear of KAZE as they do not seem to be repeatable. The $30 amazon is giving me for the error will not come close to covering double installation of my range hood.
