This product is a replacement for a 25+ yr. old InSinkErator. Installation was hampered by location of the unit in proximity to a disposal unit and the sink basin (not a fauld of the product); otherwise it was relatively simple..
My only concern is that the new unit flows approximately 32 oz. per minute which is considerably slower than the previous unit flowed. Although I never measured the flow rate of the old unit, it filled a cup much faster than the new.
