Works Great ! No issues !

### ⭐⭐⭐⭐ Excellent for the price
*by D***N on February 14, 2026*

Did not know what to expect because of some mixed reviews and the low price. Very pleasantly surprised, as it turned out. At first, I wondered why the units would not fit in their plastic mounts correctly, then realized that they would fit correctly once the 3 AA batteries were installed. So I guess the idea was that the manufacturer didn't want the units to be installed without batteries! Mounting plate was fine and not as flimsy as I had been led to believe, and the screws were also fine. The only reason the units did not get a five-star rating is because the batteries were ultra cheap carbon zinc that would probably last only a year. It wouldn't have cost that much more to put in some decent alkaline cells. All in all, very happy with the purchase, although I don't know if they actually work until I have a smokey or CO event...
