Product review (5 stars): Quiet, effective reliable. Had it for years.
I installed this many years ago and it still works fine. It is the quietest range hood exhaust I had seen. On the low setting it is virtually silent. On the loud setting it's not so bad. Especially when compared to the range hood it replaced.

Many range hoods don't do a good job of ventilating food that is cooking on the front burners, the ones most frequently used, but this one does. The front of the exhaust hood actually blows air instead of sucking it up. It pushes the air down and back so it can be sucked up through the exhaust. It actually works. Take a smoke stick or incense and place it on the front of your stove top and you'll see the path the smoke takes. This makes it more effective than my previous range hood.

(update: Mine is really old. Back when it was Nutone Allure. There are no vents on the top of mine. Only in the front/bottom near the lamps. I see now based on other's reviews there are vents on the top of the new ones.)

It says to use 50w par20 halogen bulbs or 40w R16 incandescent bulbs  which are a lot more expensive than standard incandescent bulbs. In the beginning I used the par 20 halogen bulbs but one day I didn't have any and was too busy to go get some so I threw in some regular 60 watt incandescent bulbs that are a fraction of the price. I've been using either 60w or 40w standard incandescent bulbs for years and haven't had a problem with them. They're more visible than the par20 bulbs but not bad to look at. They fit perfectly. You just have a couple glowing orbs sticking out the bottom of the hood. The regular bulbs cost less than a buck while the par20 bulbs can cost more than 10x that. I don't have the manual anymore but you might want to check or call Broan to see if they have any issues with using the hood with these bulbs.

Just like the fan switch, the lights can be turned on High, Low or off.

The two filters on this hood are bigger than my previous hood. They cover almost the whole bottom of the hood which is nice because it helps trap some (not all) of the grease from entering the inside of the hood but it makes them difficult to clean. I usually pop them in the dishwasher once a week on a Pots & Pans cycle but their size means not much else can fit on the bottom rack and I have to make sure the upper spray arm doesn't hit the filters.

I bought it because it was quiet but I wound up liking it for a lot more reasons. It can be vented from the top or back depending on your vent orientation. Great product that does what it says.
