Well, I went ahead and got the unit and installed it today. Yes, it is kinda spendy for what it is but it really is nice to have. We don't have any kids and my wife stays in the car a lot during short trips into a electronics store. This will give her the opportunity to roll down the window if I find something that takes a little longer to look at. Also added the "actual size" sticker to the back window along with the window handle from Home Depot as posted by a fellow member. Used automotive exterior tape and it is on solid.
