We have an automatic opener from McMurray; and now like it - but we had to send the first one we got from them back because we could never get it to work. They replaced the entire unit, no questions asked and no hassles, and the new unit seems to be working great. During the day, you can see a picture of it from the inside of our coop on the "chicken coop cam" here: http://www.betterhensandgardens.com/ You need to click on the Buckeye rooster picture on the left side to access the camera. We haven't had any chickens get shut out at night and it also comes with a light that turns on so that the chickens get 14 hours of light even during the winter. It's been a nice added convenience!
