Finally I can actually see we're safe
Our old detector just beeped when something was wrong. This shows me 0 ppm every morning when I wake up. That number alone gives me more peace of mind than any alarm ever did.
Got one for every floor after this
My sister had a scare not long ago, her detector didn't go off until the levels were already dangerously high. That was enough for me. I got her one of these and ordered two more for my own place. The fact that it catches low levels early is exactly whyI bought it. Not waiting until it's too late again.
