Product review (5 stars): Easy as Pie
Just as other reviewers state, this is a one two three job anyone can accomplish. Four screws, two electrical plug ins, an Exacto knife trim to open the back fill  funnel that is pre embossed for this cut out, then put the shelf back in place. I installed this in a Kitchenaid side by side and it was making ice in an hour or two. Unit arrived very fast from Pennsylvania to CA. Good seller.
