After being very happy with my Omlet coop door, I decided to buy the coop light to go with it after my flock decided they didn't want to go in the coop and I lost a hen to a predator as a result. I don't have power in my coop, so the cost of this light vs. other similar products was comparable. The light was easy to install since it plugs right into the coop door. The light is helpful for guiding the chickens into the coop and it works well so far (about a month or so). The company stands by their products, they were very good about replacing the board to my coop door when it broke due to a defective battery. I will update this review if I have any other feedback after using it for longer.
