Product review (4 stars): Overall, good buy.
Overall, nice hood for the price.  Fan is strong but quite noisy at level 3 and up.  Light is bright.  They provide a damper for the rectangular duct connection but not for the round duct connection, so you will need to buy a damper and a 7 inch duct.  According to my plumber it would make more sense to provide damper for the round pipe since that is the option most people use.

2 day delivery with Prime was excellent.
