My DW is HAPPY!!!
Whoopee
I just installed a Fabulous Operating Products range hood upgrade in our 5er. The new one on low can hardly be heard while each of the other two speed modes are way quieter then the original which sounded like a 747 on take off roll:

It also has an outside grill that doesn't have a flapper that falls off or is forgotten to open or latch as the new one closes off via a lever inside
While it was a fairly easy project, I do have to say that the step by step instructions and the thumb nail size photos supplied leave a bit to be desired and the actual fit in the hood needed some (minor) metal work to sit flush.
I bought direct with free shipping plus that saved the 14 bucks NY State tax that Amazon would hve charged me
