We have had this automatic door opener for 30 days today. It has been installed for 3 weeks. We have changed the batteries three times. Twice in the last four days. We are not sure how long the batteries had been out the first time. Luckily a predator did not get them while they were sleeping. The reason we purchased this was so we would not have to get up early to open the coop door and could be gone after dark and not have to rush home to close the coop door. The first set of batteries came with the door. The last two sets have been Energizer Max. I am not sure it the 98 degree days and high humidity have anything to do with it.I am editing this review to say that the batteries died again. Came home from a camping trip to the door not closed again. Thank goodness they were not killed. We wasted our money. Don’t waste yours. I emailed the company to ask what would be causing The batteries to die and was asked to send pictures of the string mechanisms inside.My Granddaughter and I candled some eggs today. I was pleasantly surprised on how much detail we could see with this candler! This beats any other candler by far! Our eggs had been in the incubator for 10 days. We had the lights off but it was far from dark in the room. I highly recomnend this product !It works wonderfully! My children were able to watch a chick moving around inside the egg and we were even able to take a video!Works great! Ready to watch my first batch of chicks hatch in a few days.Awesome product. Bright light. Great price.We bought a chicken coop door opener while our large coop was being build, which took longer than the warranty date. When we installed the brand new door opener, it had an electrical defect and did not work. We checked all the troubleshooting details, no go. The Titan service department strung us along for many weeks with NO advice, and ultimately no help. This flimsy poor quality product is useless. The Titan company does not stand behind their product, only providing lip service on the website, but practically has no insight or useful help. We spend est. CDN$ 120 on a new useless defective unit. Our advice is to move on and buy a reputable product from a reliable company. Save yourself the grief.Works well and priced well.Works great. Great value.Meilleur investissement que j’ai fais pour mon poulailler de ville, la tranquillité d’esprit matin et soir. J’ai installer ce système au mois de Mai 2021, nous sommes maintenant en Janvier 2022 et je n’ai toujours pas changer les batteries malgré les -32 dégrées des derniers jours. Je recommande ! Avec le capteur solaire c’est merveilleux, aucun changement manuel à faire selon les saisons.J'ai acheter cette porte automatique pour mes poules, par contre je trouve que cela consomme tres vite les batteries ? depuis l'achat, j'ai du changer de batterie 2 fois.Easy to set up! Now I don’t have to get up with the chickens...they let themselves out in the morning!
