## Customer Reviews

### ⭐⭐⭐⭐⭐ Legit fire alarm
*by B***Y on July 3, 2024*

Yes it’s as easy to install as advertised. Which was one of my main goals. The sound performance pretty good. No complaints. I do feel safe knowing I have a working, well made fire alarm in my home.

### ⭐ TOTALLY USELESS
*by H***R on December 24, 2022*

DO NOT BUY. I bought one of these in September. Went to install it and found it was already dead and would not activate. Returned it and got a replacement the following month. Unfortunately, I waited too long to install the second one and guess what??? It is ALSO a dud. Does not activate. Now return window has closed and I've just wasted 14 bucks and put more trash into the landfill. Great.

### ⭐⭐⭐⭐⭐ Smoke Detector
*by D***F on May 31, 2024*

I liked that it was so simple to install, and it doesn’t even require the screws that it came with. It just sticks on the wall or ceiling. It was well worth the inexpensive price.
