Product review (5 stars): Quality product and smooth installation.
Very well engineered which results in an easy installation.  Very pleased with the protective packaging and boxing of the unit.  The unit seems well made and a quality product. Also, very happy with the plastic transition 6" vent that was provided for installation to the main ducting.  It is both flexible and can be extended to approximately 60" so if your ducting is not perfectly aligned above the unit it allows for a great connection.  The buyer should plan on needing several 6"-7" adjustable duct clamps as these are not provided by the manufacturer.  Overall, I would recommend to others and I am quite happy with my purchase.
