Received sooner than expected. Installation instructions were comprehensive, took less than an hour. I recommend getting the crown for the top if the chimney. It gives a really nice finished look. Had some of the grills that were damaged in shipment (2 of 4 in the 48” hood). I called Z-Line and had the grills a few days later without any hassle.  I would definitely recommend Z-Line and the Range Hood Store as a great companies to do business with!!
