Product review (4 stars): Z Line KZ Range Hood.
The unit arrived in good condition, considering it was a reduced price due to outside packaging damage. There was one screw missing to hold the glass canopy. The only problem with those units is the stainless steel exhaust cover. Instead of having the base unit 20" long, both units come in 16" and when assembled it amounts to 31" total lengths from top of unit to ceiling. In my case the height was borderline and left me with a maximum hood height to the range distance.
Noise level at range 1 is adequate with increasing noise on level 2,3 and 4.
