Product review (4 stars): Very nice
This is a very nice hood. It's not too loud, even on the highest speed. I have to use it ductless, so it's not going to perform as it would if it were connected to a duct.
The installation in my kitchen was really difficult- mostly due to my cabinets (it took a couple of hours). However, a few shims fixed that problem. You will need a very long screwdriver. The screws on the right hand side are relatively easy to get to, however, the others are very very difficult to reach, both are very close to the blower assembly.  You will likely need two people to install this.  It is not heavy but it will be very difficult for one person to hold it and screw it into place.
All-in-all I am pleased. It looks great also.
4 stars because of installation difficulty and the instructions could have been a little more clear. I would recommend this hood.
