I put a lot of effort into reviewing automatic coop doors before I bought this one and am happy with this one so far. It definitely had the overall best features with a lower price tag. It's super easy to install, and the auto door works perfectly. I like the optional timer/light programming on both opening and closing. The only 2 items of concern are 1) the safety sensor on the door is pressure activated and I thought it took a lot of pressure to stop the door from closing and 2) there is a thin channel on the bottom of the frame, that the door goes down into. It seems to get filled with debris. The door still closes fine but wondering if this will become an issue in the winter. Batteries installed for 6 weeks now and they seem to be just fine. Again, winter will be harder on batteries so we'll see how they do. Overall, really happy so far.
