Product review (4 stars): Excellent Exhaust Fan and powerful
Once the fan was installed there was a metal to metal grinding sound. The service rep was very good and tried to problem solve it over the phone and I obliged. He decided to send two new screen covers that protect the fans. When I put the new screen covers  side to side to the old screens you could see the new ones were more concave and when they got installed no more grinding. Great powerful suction on the two fans and a good looking range exhaust.
