This takes a lot of pre-planning to install.  You can't just install it anywhere.  It's heavy and needs extra blocking in the wall. We had to move our outlet.  You can't center it because of the duct. There is limited space to locate the outlet, not be behind the duct, but still concealed inside the stainless enclosure.  It's quiet enough for us on low, but level 4 is great for extreme cooking issues.  The lights are too blue and not very bright.   I would love to switch them out for a 3000K LED and add more lighting at the back of the unit.
