The hood is beautiful and works great. I have a problem with the venting through the attic. I am aware that the workmen that installed the hood had very little in the way of directions for the install. What he thought should have been an easy install took a great deal more time. I am experiencing a sound from the attic that I believe to be from the installation of the hood. I will call my installer back to take a look. But the over-all product is wonderful.
