Oh yeah!
I bought my Testo 317-3 primarily for work so I was wearing it as we were organizing the crew one cold morning. I had set the alert level to 20 ppm. One of the trucks was idling to warm up and I had walked by the back of it. A few seconds later I heard what I thought was a truck door open alarm but it was my CO monitor. I know it works. I'm glad to have it because of all the poorly installed furnaces I am called on to service when the landlord's maintenance man can't fix it by replacing parts. So many times it is a poor or even dangerous installation so I need the protection of a reliable personal CO alarm. It looks as though I made a good choice.
