Product review (3 stars): check for dents carefully when you receive the product
received mine in a perfect factory box, didn't open to inspect the item carefully. when the contractor came to installed it, he found two issues: left side of the range hood was severed dented. He  also found a screw that attach a transformer like parts to the body lost inside the hood. basically that parts just hang there with one screw and caused a dent from inside the hood. Since the shipping box has no damage, I can only imagine the range hood was dented from the factory.  Wish they had better QC.
Mechanically the range hood is working fine after the contractor fixed the loosing parts and installed it, but ugly with those dents.  Uninstalling and exchanging for a good one simply isn't a good option for me. I have to pay the contractor to install a new one again.  Lesson learned: buyer should open the package and inspect for dents immediately, before the contractor come to your home.
