We've had the Ador1 for 9 months now. It is such a relief to no longer worry when I get home late, especially during the dark days of winter (we live in coon & fox country & have had flock decimations before). And, I have had no issues with some of the concerns I've seen others express: no one gets stuck in the door, the girls learned how to maneuver it within a few days, & it faithfully opens after sunrise & closes after sunset so no one is ever left outside; I don't have to use the straggler setting at all - a setting you can program that will open the door after "first call" & then close again a few minutes later to let in chickens who might not "get it" right away..
We installed it on the outside door of a completely enclosed & covered hardware wire, predator-proof run with an enclosed coop inside. This door is on the downhill & shady side of the coop (under some trees), so if there were to be a problem with the sensor not reading the light correctly, this would have been the test case: sunshine doesn't hit it directly until late morning, but my girls are up & have been let out into their free range area by early morning.
We did have an issue of battery drain when we first got it, but we are more than happy with the quick response & part replacement we got from Rod (owner). It doesn't mean we don't still have our morning & evening rituals, just that if we're late getting back from town or want to take a weekend off, our girls are safe.
