Product review (3 stars): GOOD --- but slightly oversized.
This product would have a 5-star rating if it were accurately SIZED.  One of the dimensions is about 1/8 inch too large so it becomes a struggle to insert this into the slots of the range hood.  (The size problem is further confirmed when the replacement is laid on top of the original Broan filter!)  Well... as least the replacement is a tight fit once inserted... so there is minimal leakage of unfiltered air.
