Replaced both the ice maker above and this unit. The video provided by this company for this unit made the job easy. I watched it several times so I knew what to expect and it was easy to follow. I don't know why others bought parts for the water lines as these were identical and even had the black lines marked exactly where they needed to be as in the video. I asked via chat about this, and the person online was extraordinary. I can't recommend this company more.
