Product review (5 stars): Now turning on the vent to the second or third level of power results in continued good air quality in the kitchen
Haven't you always smelled what you cooked an hour ago and wondered if it would be a health concern later on?  Now with the range hood, the kitchen air smells not of what was cooked anymore!  After having taken several weeks to install the unit, given we had to get several contractors to 1) install electric supply 2) bore a hole into the wall and 3) attach the unit firmly, the unit is up and running and doing well in serving its intended purpose!  Now cooking eggs or pan fried food doesn't result in reflexively opening up windows and closing doors.

PROS:
1) Strong and reasonably quiet motors - This unit does move air, and I ran an anemometer calibrated to the outside opening registering 737 CFMs.  I have a slightly smaller duct out given building constraints and was not able to utilize an 8" opening, so I ran an elbow tubing as large as possible before the smaller outgoing duct.  Now turning on the vent to the second or third level of power results in continued good air quality in the kitchen.
2) Noise level - Not totally silent, but more like an air conditioner in a car turned up to medium high level.  This is comfortable sounding, and the frequency is more like a low rumble.
3) Sleek and professional look - Stainless steel that is easy to clean.  Also the grates underneath the hood look magnificent.  May be a little tricky to manuever out for cleaning, but rather have that than falling down easily only your cooking project below
4) LED lights add a nice touch, lighting up everything below.  Keep your cook top clean too, as it will light all the stains as well that was previously hidden in the dark!

CONS:
1) Heavy and setup required 3 grown men - Definitely not a one person gig.  We didn't do the carjack method either! Instead 3 people did the trick, and long specialized screws were used to make sure it was secure.
2) Attached power cord is shorter than expected

This is the second range hood we have purchased so we knew which factors were important in our decision.  We examined all the other offerings on Amazon, and based on the build quality and stats for a higher air flow rating, as well remote control features, this unit was picked for coming out on top.  Overall, a good product that does a really good job of maintaining the kitchen air quality without breaking the bank.  Setup was the only difficult task, but as a one time process, not something that was unexpected.  I would recommend this range hood for those needing stylish look with functionality.
