Product review (4 stars): Nothing is made like it used to be
The plastic bladed fan is rather effective in moving air up and out.  The construction of this is just OK.  The metal is very thin and there are lots of sharp edges on the inside.  The hood is not quite square and is about 3/16 wider in the front than in the rear.  I also had to use lots of metal tape on the inside to seal all the extra holes and the mounting holes.  I had to seal the exhaust hole for non-vented installation too as the plastic diverted leaked.  I guess the old adage is true...Nothing is made like it used to be.  Honestly I'm not sure if there is a big difference between this sub $200 fan and a sub $100 fan.  I guess if you want a real hood that really moves air you have to step up to $800 or so.  That being said this was a OK value in the sub $200 range.  The lights are a nice addition over some of the cheaper hoods.  The lights allow us to keep the kitchen lights slightly dimmed while lighting the range quite effectively.
