Product review (1 stars): Manufacturer's Quality Control - Needs Work
After researching hood vents, we were thrilled to find that Z Line had everything we were looking for.  We ordered the 36" model and waited for delivery.  Unfortunately, the box was mislabeled and contained the 30" model.  We were hesitant to have another one sent; thinking that if one is mislabeled, they all might be (placing the box next to a larger model, it is clear the box is smaller).  Deciding to give them another chance, I called Amazon and they quickly replaced the unit.  When the new hood arrived, we were much relieved to find it was the correct size.  Relief was short-lived as there was an issue again.  This time the fan motor was incorrectly installed by the manufacturer and made a horrible screeching noise when turned on.  Apparently it was installed off-center which placed it next to the metal safety guard (imagine the sound of metal against metal at a high rate of speed).  The company needs to implement better quality control.  Our advice is to go to a showroom or box store and purchase directly through a reputable company.  We've ordered many times from Amazon with no problems, so not sure if the problem was with Z Line or Amazon.
