Injured my chicken! Extremely dangerous and misleading. This item falsey advertises "infared sensors" that supposedly detect any blockage (your chicken) which prevents them from being crushed. However there are NO infared sensors, just a motor designed to roll back up after a significant amount of weight. I tested with an empty can and it dented it quite a bit. This is very misleading and dangerous. I didn't have a faulty item, since it was working as intended but its crushing force is too much. one of my chickens got crushed and although she will live i had to take her to the vet for an injury.
This item should be taken down for safety, because again, there are NO sensors and i checked the entire thing. I even took it apart to see.
Dont risk your chickens lives and get a door with an adjustable anti pinch option!
