Product review (5 stars): Great little hood for the price!
Our builder-grade (G.E. brand) hood bit the dust so we bought this one.  Fully expected I'd have to hire an electrician, so we "uninstalled" our other unit to save time (because electricians charge by the hour).  When we got it out (four screws!) we looked at it and figured out that we could re-use the other unit's electrical plug on this unit (we have an electrical outlet in the cabinet above our hood) so we did.  It took my husband and I about 30 minutes to install (one holding the unit, while the other one puts in the screws).  It is versatile, too, because you could use it on just about any kind of vent (round or rectangular) and it fits beautifully.  It is SOOO much quieter than our other one, and you can actually feel the air rushing past your hand when you turn it on(our other hood was never that efficient!) Checking online for other prices, the cheapest I could find was about $150 or thereabouts, so imagine my surprise when this one arrived in perfect condition, and was so easy to install!  Awesome!  I have a light and a fan again!  Yippee!
