Product review (2 stars): It is mounted correctly at the ceiling on a very sturdy 2x4 system tied directly to the 2x10 floor systrem ...
My new Z line island hood does not meet my expectations.  The motor is not quiet as advertized. The mounting system is flimsy and does not have a solid feel.  In other words it "giggles around " when touching it to cut on and off etc....  It is mounted correctly at the ceiling on a very sturdy 2x4 system tied directly to the 2x10 floor systrem above.  That can be fixed with some more metal straps etc...  The loud fan is the main issue.
