I'm glad that I went with this brand over a cheaper one. Easy installation and loud compared to my previous one. Green flashing light means I can sleep at night

Fire alarm? More like humidity alarm
I bought this alarm because it was supposed to have less false alarms. Joke's on me, though, because it has more than any alarm I've ever had. This stupid thing has gone off due to the microwave, a boiling tea kettle, the shower, a thunderstorms, and, my personal favorite, absolutely nothing. Three stars because it works (I mean, I hope it would actually alert to a real fire, but I'm beginning to wonder if that's the one thing it might think is fine) put zero for waking me up in the middle of the night for no reason.

Terrible, Horrible, Cheap . . .
Horrible! I replaced my older models with these, and it's very difficult to change the batteries. One of my units was defective and ALL the alarms go off in the house. I think I have hearing loss from the noise. Do not buy these. I can't believe I spent good money on these pieces of junk.

The boxes are damaged and I am likely going to return them.
