Installed the door (including the solar cell, photosensor, and cleaning up all the wire runs in the coop) in about an hour. Cut the hole, bolt it into place and connect everything. It really is that simple. To cut the hole in the side of our coop, I traced the opening, drilled some large holes at each inside corner, and then used a jigsaw to cut along the lines and "connect the holes." I mounted the solar cell on a south-facing wall which will get full day's worth of sun.
The chickens won't be in the new coop for another couple of months but I still get a kick out of seeing the door open every morning. The only thing I've run into was the door freezing shut in a recent snow/ice storm. I went out in the morning to see and it was still closed thanks to all the ice. I thawed everything out with some hot water and used the little magnet (included with the kit) to manually open and close the door a few times and it worked just fine. I will probably install a small awning or roof over the door to keep out as much rain and ice as I can before next winter.
