It's hard to say yet as it has not been installed.  I trust that it is the quality as portrayed on your website!
Well, it's been installed for a while now.  It's VERY loud, however, and difficult to carry on a conversations when it's running.  The sone level stated here is certainly not demonstrative of the noise level created.  Exhaust efficiency is adequate, but not super duper.  For the price it is sadly not up to the standard I expected.
