I'm very happy with my Run Chicken door. My coop is attached to a secure run. Makes life so much easier since I do shift work.
It can run off a light sensor or you can set it to open/close at a specific time.
We installed the Run Chicken door last summer, it's such a blessing. Especially when we have to go on vacation, all we need ask our neighbors to help is to collect the eggs, and add feeds/water every few days. Asking someone to come to the coop twice a day is quite a chore/favor to ask.
Highly recommended - easy to install and we simply use the default option (open/close 20 min after sun rise/set. ) We have not replaced the battery yet. It's been almost 6 months.
