Product review (4 stars): Requires lots of disassembly/reassembly
great looking hood fan but it was not a walk in the park to install.  I have a center 7" vertical duct and it was required that a lot of the insides had to be removed to configure as a vented hood.  Non-vented configuration would as involve removing and adjusting inside parts.  I also had to duct tape inside to prevent some blow back / air leaks that were occurring (which involve taking insides out again).  Fan is quiet and lights are great (I used LED floods instead of halogen).
