Rated 3.8 out of 5 by 34 reviewers.
Rated 1.0 out of 5.0 by Lasts one year max, MADEINCHINAJUNK I bought 6 of these to cover all the rooms in my house. Within exactly one year, all six of them starting peeping and chirping to indicate a low battery, all within one month of each other. There is no way to stop the chirping (pressing hush does not work). There are no batteries you can change. I had to throw them all out. A total waste of 150 dollars. I will never buy a Kidde product again. It is junk. September 3, 2014
Rated 1.0 out of 5.0 by Awful I bought 4 of these one for each bedroom after two weeks one would go off high screeching chanting fire fire nothing. This happened three times so I took it down and put it into the same room as another one. This time it kept going off and you can't. Pop a battery out to shut it up and the hush button didn't work. Finally I had to clip the wires I could see through a small opening. I exchanged it the next day. Then it started on another one. So far all false alarms during the day but then early this morning it started in, it's so loud. My 25 year old autistic foster son went flying out the door I could not hear that because of the smoke alarm, then the ADT went off because the young man went out the door. It was so awful it was almost funny. I took all fout back to Home Depot this morning and ordered the old fashion kind. June 26, 2014
Rated 3.0 out of 5.0 by I like the voice, but not the mounting base The mounting base on this is very strange. It is about the size of a USA 50 cent piece. I don't like this, and I had some issues with it on a popcorn ceiling. You have to give it a good twist to activate the unit, and it feels like I'm going to rip it right off the ceiling. (See attached photo.) OK, so they tried something different by having two different ways to mount it, one with traditional screws and anchors, and the other with a central drywall anchor screw. Neither gives me much confidence. Mounting issues aside, the unit has a pleasant voice announcing "fire" in a direct tone. This is good for someone who may have issues, such as dementia. It makes it clear what is happening. I've only had it up a few weeks. We'll see how long it lasts and I'm hoping for the best in longevity. July 6, 2014
Rated 4.0 out of 5.0 by Im a little skeptical on this... I am an old timer that would prefer to use the ones that you can replace the batteries with. My alarm (this alarm) goes off often because where I have it and my kids often burning things in the kitchen. I have it in my living room but rite outside the kitchen. I am a little concerned that the battery might not actually live it's 10 year life. This is why I like the old style, but hard wire. Tho it was easy to replace and looks nice otherwise.

Rated 1.0 out of 5.0 by Did not work at all This device is suppose to have a 10 year battery life. The battery was dead when I opened the package. July 22, 2014
Rated 1.0 out of 5.0 by WORST alarm ever! I've had this less than 5 months and it has started going off. Hush doesn't want to work. The only way to shut this thing off is to disable it and then you have to throw it away. If this is the future of alarms we are in trouble! I want my regular old change the battery every 6 months alarm! November 28, 2013
Rated 1.0 out of 5.0 by Constant steady 85 dB first night I had it And I could only turn it off by disabling the alarm for life. NO GO for this type of alarm. January 12, 2013
Rated 1.0 out of 5.0 by Find something else 10 years? Hardly. Lasted 4 months. Tried cleaning with vacuum yesterday as directed in instructions and this morning the alarm went off again and now hush mode wont work. Find another brand. Kidde has lost my trust. October 7, 2013
