Rated 4.0 out of 5 by 2 reviewers.
Rated 3.0 out of 5.0 by Internal Equipment Issues I bought Like 8 of these and 1 of them went bad within a matter of a few months. It just started beeping nonstop. Although it was quite loud but it was a pain because I had this detector installed quite high on the ceiling so, if you disconnect the electricity it still works do to the battery which is placed within the detector. I wanted to return the product but I couldn't return it because the warranty was void. Also, it is quite pricey wouldn't recommend it to anyone. . December 29, 2012
