Product review (4 stars): Looks good, works quiet, almost  perfect.
The Broan NuTone QP230 line of Range hood are very good.
-The unit looks awesome, and it operates almost silent on the lower setting while moving a good amount of air. Even the mid setting is not that loud and it does move plenty of air out of your kitchen.
-I found an issue with the this unit motor and fan placement. It sucks a lot of air from the left side but not from the right and that is where the stove power burner is located. The power burner is used the most in our kitchen (- a star).
-The halogen bulbs do get mighty hot, as hot as the food you might be preparing. I knew this and I replaced them with LEDs even though Broan does not recommend it. You will save a lot of energy too. I got the Triangle GU10 LED Bulbs T95031&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Triangle-Bulbs-T95031-LED-6-Watt-Dimmable-GU10-MR16-38-C2-B0-High-Power-50W-Equivalent-Warm-White-Light-Bulbs-UL-Listed-Energy-star-certified/dp/B00LTY73SI/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Triangle Bulbs T95031 - LED 6-Watt Dimmable GU10 MR16 38 C2 B0 High Power 50W Equivalent, Warm White Light Bulbs, UL Listed, Energy star certified</a>. You might not see that difference between the halogen and this LEDs (see images).
-The unit has some weight to it, so you might need someone to hold it while you are mounting it. Also you might need to remove the lights housing since the screw holes are too close to the sides and it might be a pain to insert the screws. I marked where the screws were going, placed the screws almost all the way in, slide the unit and then finished tightening the screws.
-A word to Broan (the manufacturer): In this day an age you should be thinking about energy conservation, so it will be good for the environment and to consumers wallet to start using LEDs on your products instead of the flaming hot energy hogs halogen bulbs.
