We purchased this automatic coop door early in the year, 2020. It was pretty easy to install and setup.After several months with ZERO issues it stopped working and would not move at all or make any noise like it was trying. The support folks sent me a new circuit board to try and that did not fix the issue. They then said it would take a few weeks to get another motor/rod assembly in due to the demand. I mentioned it would be freezing here soon and "Dolly" said she would see what she could do. A week later I received the part and it worked!Now, after thinking about it I believe the chickens bumped a small block of wood into the path of the door as it closed and just blocked it a tiny bit at the bottom., over a bit of time I think this caused the motor/gear/rod to fail. Soooo, keep that in mind when you install the unit, make sure the door way stays clear with a bit of room at the bottom.We love this product and the support was great. I rarely do reviews but this one deserved it.
