Review on 🔥 First Alert CO710: 10-Year Battery & Digital Temperature Display CO Detector by David Banks

My previous one died about a week before so I ordered this one which looks like a good one - good brand, good display. After reading the instructions, I set it up, which only took a few minutes. It started beeping, which I thought was normal when it first started. He said to evacuate and alarmed and talked about the evacuation for 3-4 minutes. Powered off, read manual, restarted. He did the same, so worried I left the house, went to the porch, called 911, and took the detector with me. He continued to disturb even when he was outside. Firefighters checked and there was no carbon monoxide in my home. Two fire departments. The staff stood outside while another checked my house. They were there for at least 15 minutes and had a detector sounding the alarm the entire time. They found it was defective. I returned it.
