Bird In Hand Pet Structures - Advanced Auto Door

I bought the advanced model so I could use the additional features and got the entire door although the motor itself is available at a lower cost.
Have had only a couple months so we will see long term how it goes, but very pleased with it so far.
Cheapest place I found was Fleming
I love the fact that it allows you to open in the morning however long before/after sunrise and close however long after sunset with no worries.
It knows your location and adjusts throughout the year according to sunrise / sunset tables for your location.
Electric with battery back up. If you hook solar panels you can run off batteries alone.
