The range hood was the second one I ordered it came by Fed Ex who dumped at the foot of the stairs in the RAIN and didnt bother to ring the bell or knock on the door. Luckly I checked the noise heard of the box dropped. I opened the box and it appeared the unit was used `since the screw mounting holes had scratches on it the backing was pulled back and torn the electric cord was unevenly wrapped the pipe hole tape was not clean wrapped the previous one I got had a 6 inch pipe clamp to secure it. The edge on one side was rough not smooth stainless steel. The noise was a bit more so put tape around the edges of the filter so would stop ratle. So not very impressed with this shipment.
