Has anyone purchased from Fleming Outdoors the "Hen House-Automatic Chicken Coop Door-Basic" ? I have seen alot of reviews on this site about the Ador1 pop door but I am concerned because we have a covered run and a lot of shade around our coop door. I liked the idea of Fleming's coop door because it is electric w/battery back up and we already have electricity to our coop. I am wondering before dropping this large sum of $$$ if any one else has had experience with this particular door?
