I had a Titan Incubator automatic door opener and it lasted only about eight months before the sensor and display screen went and it started opening the door in the middle of the night, and wouldn't close at nightfall. I'm lucky I didn't wake up to a fox attack. It had a mind of it's own so I had to stop using it. Titan wouldn't believe me when I told them, and wanted me to send them pics of my set-up, and of the back motherboard while the engine was running with a counterweight of so many grammes, they also wanted me to carry out other tests with the sensor... basically jobs an engineer would do. I did all the tests and it still wouldn’t work. I sent it back and they sent me a new one but refused to refund my postage. They told me there was nothing wrong with it...they never believed me in the first place. Poor customer service with a useless product. I have heard that ChickenGaurd are brilliant, so I will be buying from them in future. On a positive note, I swear by having a reliable one. It beats getting up at 5am in the middle of the summer to let the girls out.
