I want to give a big thumbs up for the pullet-shut chicken door company. I’ve had my door for 4 years and it works great. I had to disconnect it for a bit bc of a neighbors dog. When I plugged it back in I mistakenly connected the cold wire to the hot. Big mistake on my part! When I called pullet-shut and told them what happened they were still willing to honor the warranty and had my information right at their fingertips. No probing questions, no I’m sorry but we can’t, no phone transfers, just friendly, knowledgeable and patient help. They new exactly what to do. They walked me through opening the circuit board and removing it. The best news is that it will cost less than $40 to fix it. I’m tickled pink. I thought I would need new everything but the actual door. They also have new products...I went ahead and bought a photo sensor so I don’t have to program the door when to open and close. Lol I’m not related to them, don’t work there and I received nothing for this review. Just a good door and wonderful customer service. Thanks Pullet-shut!
