Product review (5 stars): Excellent hood exhaust with two speed fan and traditional bulb ...
Excellent hood exhaust with two speed fan and traditional bulb ( no included )on/off switch.
It allows you to vent exhaust from middle of the hood upward or to the back.  You'll need a duct reducer adapter that goes from
3.25 x 10"  to the size of duct pipe your venting to.  I vented straight up so below is list of items I needed to make this installation complete.
I had everything already but the 3.25x10x6 hood adapter which I purchased at Lowes.
Hood 6" adapter will not fit into flexible or any ducting without being crimped.
Other option to purchase a 6" male / male duct that is made for two 6" duct pipes to be connected.
Use foil tape to secure duct together, tape around hood and adapter for good seal.
All of these items can be purchase on Amazon or at Lowes / Home depot.

CON - Horrible shipping by Amazon.  I purchase a lot on Amazon and usually they always place factory boxes inside another box.  Well unfortunately they didn't on this flimsy packaged hood range vent, UPS delivered damaged, left side crushed.  I managed to straighten good enough for a rental house I own and it looks and operates better than the one I replaced.
