Fan is quieter and seems to * the exhaust out better. This fan is also quieter than the one i replaced. It is better priced then anything at lowe's or home depot for the amp.

This fan seems to be intended for new construction, where it's nailed/* to a rafter before the ceiling sheetrock is installed. Just needed to rotate the housing 90 degrees from its original orientation. Had to replace my old vent fan and light only.

The process to retrofit one of these units in a large apartment building is not for the feint of heart. A typical piece of * from china, no qc. Totally disgusted and disappointed.

Box was creased and in turn the unit housing was damaged. When you see the broan dimension schematic they show the duct fall within the case width. Once attached the duct sticks out.
