Customer Reviews for VEVOR Carbon Monoxide Detectors, 0-1000PPM CO Detector with Audible & Visual Alarm, Portable CO Gas Meter Tester with Temperature Sensor, LCD Backlit Screen for Home / Industrial (3 x Battery Include)

Live in an older apartment and worried about the boiler putting off an odor

Easy fast and worked

It could use more explicit instructions.

I was feeling sick and couldn't figure out why, so I brought back out my air quality tester (that is now in the garbage), and it signaled to me that the CO was extremely high in my room, scared the crap out of me, got this overnighted to me, this thing is awesome, well built and seemingly very accurate.

Always wondered if my gas fireplace leaked gas.... the answer was yes! This tool found the leak and I called a professional to fix it! DONE! I will sleep good at night now.
