Product review (4 stars): Looks nice, works OK
I bought it not at amazon but at local retail store.
Looks nice, works fine, but I can say nothing about reliability because I installed it just a few days ago.

My old range-hood was extremely noisy comparing to this one, but if you think this range-hood is so silent that it could barely be heard than you are wrong. It does produce quite a bit of noise  but it sounds more like noise of the rushing air than like electric motor.

Our old range hood had regular 60 watt bulb and we had a very bright light over our kitchen range. This range hood comes with two sort-of LED pot-lights that produce less light and illuminate only front part of the range. These LED lights look sexy but they are very insufficient for us.

About eliminating bad smell from your house:

My old range hood was probably around 100 cfm and it was practically useless in removing bad smell from the kitchen; this range hood is rated as 720 cfm and if you think it completely eliminates any smell spreading from you kitchen to the rest of your house - than you are wrong. This range hood certainly does better job by removing more smelly air to the outside but when my wife bakes in the oven (for eggplant salad) chunks of onions, chunks of eggplants and garlic the smell of this still spreads around the house. Two things are worthy to mention here. First, if your AC or furnace is ON than the blower fan will cause an air circulation in your house causing smelly air from your kitchen to spread all over your house. So, you are better to turn OFF your AC or furnace when you are cooking really smelly stuff. Second, if you have doors in your kitchen than close them when cooking smelly stuff and running the range hood  it will help a lot. If your kitchen doesnt have doors and you hope than $1000 investment into this range hood will completely eliminate any smell in your house originated from the kitchen than you will waste $1000.

About installation:

First, it has so-called knockouts for screws/bolts (and knockout for wires on electrical box). These are not real knockouts and you cannot knock them out using screwdriver and hummer, don't even try or you will damage the unit. These knockouts are only to indicate where to drill the holes for the screws/bolts; yes to drill in stainless steel (and installation instructions clearly state it). So, you have to have (or buy) drill bits capable of drilling through stainless steel.

Second, it is much heavier than less expensive range-hoods. Alone you cannot hold it and screw it to your kitchen cabinet - you must have someone else helping you.

Third, it arrives prewired so that wires come out from the top of the range-hood. I used these wires to wire the range hood and I didn't drill hole in electrical box (to connect wires inside it). Rewiring of this unit looks really challenging. Wires coming out from the top originate from the electrical box (inside the unit) and they are attached with clamps to the back wall deep inside of the range hood. I did not try, but I think it would require removing both motors and fans to rewire this unit. Also, instructions assert that first thing after opening a packaging box (and before doing anything with the unit like drilling holes  or you cannot return the unit) the unit has to be powered and tested (both fans and lights) and these prewired wires come very handy (I used them to test the unit).
