Product review (5 stars): Great range hood
This is a great range hood for the money.  I read the prior reviews that said they had problems installing the unit, but I found the installation to be easy.  It should be just as easy for anyone else with reasonable mechanical skills and a few good tools.  I found my Dremel tool with a cut off wheel to be especially handy for cutting the tabs on the duct vent opening.  I also read the reviews that said the unit was too noisy.  Sure it makes noise, if you turn the variable speed fan all the way up.  I found the air extraction to be very excellent at lower speeds, and I really do like the continuously variable speed feature.  On the whole, I find the unit to be very quiet compared to other range hoods I've had and just as effective as units costing hundreds of dollars more.

Aside from the product quality, it should be noted that when the FedEx man secretly dropped off the unit at my front door and left, I discovered that the shipping box had been broken open.  As a result the parts bag with all the mounting screws was missing.  I called the manufacturer about the missing parts bag and they sent me a replacement bag with no fuss or arguments in less than a week at no charge.  Gold stars for them.
