Product review (2 stars): Fan is not centered
The fan position is not center to cover even ventilation of my 4 burner stovetop. Fan is on the left side so it is not as strong for right side burner fumes which are the ones I use most on high or low setting.  When I do Kleenex test on low, the tissue doesn't get suctioned to vent on right side...only on high does right side get pulled up.  Tissue does get pulled up (barely) on left side on low.  Low setting doesn't seem to have much effect.  The high power works OK.  I wish the fan was more centered to cover my favorite front right side burners.  Not as powerful as I hoped.
