Product review (4 stars): What we needed
We had a ceiling fan that went into the attic for over 15 years.  We thought by the vent in the attic it was connected but it wasn't.  My husband and I decided to do our first upgrade in our kitchen.  He took the new hood out straight to the roof with attachment that were not expensive to add and spent a few hours making sure it was done right.  My home is old, over 55 years, and we still have cloth wiring, so I got a licensed electrician to over see his work and after a few minutes it was on.  We love it.
