## Customer Reviews

### ⭐⭐⭐⭐⭐ Inexpensive easy to install anywhere
*by M***S on April 5, 2025*

Great price easy to install but they will not pass the fire department smoke alarm certificate other than that best deal of a four pack online end of great quality

### ⭐⭐⭐⭐⭐ Works great!
*by D***  on May 1, 2025*

It’s very loud which will get anyone’s attention. I like the fact it takes double A batteries. I always have those on hand

### ⭐⭐⭐⭐ 02CO2 alarm
*by K***S on February 28, 2025*

Best to buy locally. Equal price, but not equal value. By locally easier return. Constant beeping can’t be muted. Turn off the beeping and the thing doesn’t work. Sometimes I make the worst mistakes and this is one of them. Finally shut out the beeping and had a small fire, and only the cat alerted me to the smoke in the house when I got to the smoke alarm it was beeping, but it was beeping a little bit louder than the normal beep beep beep beep beep. I would not recommend this one to anyone. Thankfully the fire was very small and no damage was done. Cleanup was a chore
