## Customer Reviews

### ⭐⭐⭐⭐⭐ I buy again
*by T***R on 17 May 2026*

Work as it should has a 10 year battery after 10 years the detector will stop working

### ⭐⭐⭐⭐⭐ No issues.
*by M***S on 14 June 2026*

Easy install. No false triggers.

### ⭐ NOT WORTH IT! Literal junk and a waste of money, not gonna keep your family safe 👎🏻
*by H***N on 13 May 2026*

I can’t believe what a disappointment this alarm is. Random false fire alarms defeats the purpose of having one. It scared my dog really bad too. I am so upset by this I felt inclined to warn the public. I guess it’s common in these newer models from what I read. The back of the alarm states that the alarm cannot be reactivated once you deactivate it. Lies. I was able to switch that on and off, which I’m guessing it’s not supposed to do. I used to trust this brand, as I had some of their alarms in the past with no issues, but now I question the entire brand. You can register the alarm and request replacement, but they gonna replace it with one that actually works though? My faith in first alert is shattered, and I’m afraid I can’t trust this brand anymore. I am now out the money and need to seek out a reliable brand so I can keep my family safe. Fast-fashion-style piece of junk alarm. Just pumping out trash and calling them fire alarms. 👎🏻👎🏻👎🏻👎🏻👎🏻
