So far so good. Easy to install with husband's help. Have adjusted the closing time with no problems. like the feature of being able to close it ahead of timer if you are in the garden and they are all in, and you are a bit paranoid like me. The chickens seem to like it. One took a bit of persuading. The door has dropped abit in its open position so i need to look at the video and sort that out, but not enough to effect its effectiveness. I hope I'm not jinxing it by being so positve, but the only negative thing is perhaps you do need to clean out the area where it closes as it won't close properly otherwise (stays open about an inch), but I do this about every three days. A very good thing, and the video explaining how to set it up is excellent.
One last thing, it makes life so much nicer in the mornings, especially when the weather is not nice. I still go out there but when it suits me, and it is surprising how liberating this is.
