It does not work period.  I had a professional installed the hood for me, the first day I start the fan and I see all the fumes going pass the vent so I opened the covers and the fan was just making noise, it was not actually doing its job.  I paid 299 for this hood and on top of it I had to pay another 150 to get it it install.  Value out of 450 dollars is 0.  All this is a noise making machine.
