The service provider scheduled the install for 8-10 am, but put it in their schedule wrong.installer did not show up until 1200. The lost work hours I wasted waiting doubled the cost of this install for me. I will never use Home Depot installation again. The point of using them is convenience and the hope that they will use their buying power to procure reliable service. So this kind of service pretty much makes using Home Depot... Useless.
