Product review (5 stars): Where product and price make sense!
Nice fit and finish on this hood makes it a VERY good purchase from Amazon at this price.  And yes the fan it a bit noisy at full throttle but you have to expect that coming from ANY hood with internal exhaust fan.  The good thing is that it gets the job done effectively so you don't have to keep it at full throttle for long.  Installation can be done by a capable person alone but the unit is a bit heavy.  It is an easy two person install!  As for wiring it up...either hard wired if you have some slack on the current Romex in the wall or just wire it up and plug it in using a "dishwasher hookup" plug or similar.
