Review on 🚨 Digital LCD Display Carbon Monoxide Detector Alarm with Voice Warning - Battery Powered by Brian Cox

I am so thankful I bought this carbon monoxide alarm. I have a Ford Explorer and was a little worried about a carbon monoxide leak that I've heard about since I was a baby. I leave this carbon monoxide alarm in my car to make sure my child is safe. Last week as I got into my car I heard the alarm go off. I looked at the detector and it showed that the values were really high (325 and up). The detector sounds an alarm and also offers to open windows and doors and look for fresh air. My Explorer was parked in my closed garage and the engine was off, so I knew it wasn't the car that was causing it, it was something else in the garage. As soon as I opened the garage door the numbers went down and the alarm stopped but it definitely startled me a little. I never found what made it work.
