Review on Fast Low-Level Carbon Monoxide (CO) Detector for Cars, Vehicles, and Aircraft - 9ppm Alarm, Ideal for Police, Pilots, Travel, Buses, and Trucks, Compact Metal Body (2oz) by Matt Simpson

I drive a 10 year old car and because I drive a lot I wanted to know if carbon monoxide got into the cabin. I received and tested this little device to make sure it works. I set it up next to burning incense when I saw someone demonstrating on YouTube and the monitor immediately responded with warning lights and beeps. This gave me different readings depending on the distance from the incense burner, and I was surprised at how much CO I was exposed to, even from across the room. This is definitely not safe, especially in small spaces with poor ventilation. When tested in my car, the monitor never moved, so I am now absolutely confident that my car is safe. This monitor is small, well built and will now accompany me on my travels. If you are looking for a CO monitor and don't know which one to choose, I highly recommend this FORENSICS device.
