Review on 🚨 X-Sense CO03D Carbon Monoxide Alarm Detector: Battery-Operated CO Detector with LCD Display by Larry Willis

So I bought two of these to add to my six smoke alarms and RC01 remote. All new devices can be connected to each other and controlled remotely as easily as possible. Four stars for how because I didn't have one to disable the alarm and other reviewers say ppm stays at zero. After some research, it turned out that devices take a long time to trigger the alarm on the back of this device. The alarm is said to take 4-15 minutes at 400ppm to go off. I still have a long test to do. However, my smoker has changed the ppm, as has my car exhaust. As with other reviews, it definitely works, just need to do more testing soon.
