CUSTOMER REVIEWS

Rated 4.1 out of 5 by 31 reviewers.
Rated 1.0 out of 5.0 by Battery DOA Purchased 2 of these unit, one of the packages was beeping non-stop (still in packaging). Once I installed it, which a bit of a trail because of where the old alarm was, the unit said battery something or other. According to the packaging this battery should have a 10 year life, will it didn't even have a few minutes. The other unit so far so good but I'm wary of the unit, again too much of a pain to remove if not absolutely necessary. Notice other feedback says units batteries are also DOA. This one of the most expensive units available at HD. Battery should be protected until actually installed then activated, pull-tab or something like that. January 21, 2015
Rated 1.0 out of 5.0 by Lasted less than 2 months Sensor started low battery alarm after less than 2 months January 14, 2015
Rated 1.0 out of 5.0 by Low battery Installed and right away low battery starts beeping. Why package products that aren't ready. Now have to travel all the way back. November 2, 2014
Rated 1.0 out of 5.0 by Garbage!!! I bought two of these and both batteries are low. The units are no good! They both cherp constantly and provide a voice alert that the batteries are low. I have had the units for only a few hours. Do not buy!!! March 25, 2015
Rated 5.0 out of 5.0 by A Life Saver Combo smoke/carbon easliy installed. Best part it has a 10 year battery back up that does not require changing!!! March 25, 2015
Rated 5.0 out of 5.0 by Easy install with voice alarm for smoke and carbon monoxide threat. Installed 6 interconnected throughout house a month ago. So far no false alarms or any beeps indicating a low battery. Appreciate having CO monitoring in every room . . . especially the bedrooms. I like the verbal warning that distinguishes between a fire or carbon monoxide threat. Not having to worry about battery replacement (and low battery chirping) for 10 years is a great convenience.

Rated 5.0 out of 5.0 by Seems good enough to me. My electrician had no issues with installation..... March 3, 2015
Rated 1.0 out of 5.0 by Low Battery?!?!? I am getting ready to make a 3rd trip to the store to return another set. Currently I have had 50% success with these the other 50% immediately report low batteries. December 12, 2014
