Thinking about getting one of these ador chicken doors, sounds like most of you really like it with little issues. I now have a solar one that runs on double A's and it was worked great for about a year and a half, just quite on me. Tried replacing the batteries even tho the ones in it where pretty new. Still not working. I got mine at Foys I can't recall the name. If I can't get it going again this ador is looking good!
I've been happy with mine. I did get the external light sensor ( mine faces into the coop run), and it opens early and closes late.
