### ⭐ 1.0 out of 5 stars







  
  
    Defective
  

*by M***N on Reviewed in the United States on September 25, 2024*

have had for 32 days, missed return window by 2 days. This one beeps after 30 minutes with the same CO2 warning of 061. Always the same number. Started on Sunday, the 30 day return window. Have another unit exactly the same make and model. They are plugged in outlets 4 feet apart and the 2nd unit does not have any warnings. For $70, think they should last more than 32 days.

    Every one should have one as well as a smoke detector.
  

*by P***I on Reviewed in the United States on March 4, 2018*

Have had this Universal Monitor in use for the past 10 yrs and it has served its purpose. Twice it has alarmed when there was a problem that could have been dangerous situation. I highly recommend the use as it serves a double duty.

    Faulty! Don't buy
  

*by G***R on Reviewed in the United States on March 28, 2020*

This company makes faulty detectors. I recently had one go off indicating a carbon monoxide leak. I immediately called the fire department and upon inspection of my home, I was told there was no leak and that the detector was faulty. I'm calling the company and demanding my money back. This is disgusting.Update: Company offered me replacements.... I blatantly responded to a reps email asking her why would I want more defective crap? I am now up at 1:30 AM because the 2nd one I bought started beeping. We didn't call the fire department but replaced it with a First Alert detector we had and so far, no beeping. This is unacceptable and I'm going to get to the bottom this somehow with reporting them to the proper authorities. This is insane.
