Rated 3.5 out of 5 by 41 reviewers.
Rated 1.0 out of 5.0 by Great Idea, Defective Execution I purchased four of these "10-year" smoke detectors and in less than a year thinking the extra cost would be recovered by the savings of 9-volt batteries needed with traditional smoke detectors. Unfortunately, two of them have gone off erroneously and because of the design, you can only turn these off once which is permanent. I have tried to contact Kiddie and that have not responded. I still like the idea of the 10-year battery smoke detector, but I will never buy Kiddie again. June 27, 2015
Rated 1.0 out of 5.0 by This alarm will give a false emergency beep and will never stop until it is destroyed. This is the 3rd Kidde smoke alarm that has failed. The 1st one would go off with no smoke or fire and would not turn off. We took it back and The replacement did the same thing a couple months later. This is the 3rd one. We put it in the kitchen, and it did go off due to a small amount of heat or steam from the but it would not stop even after activating hush mode. Hush mode should work for 10 minutes before beeping. This would hush for about 10 seconds. We put it in a new room and it would not stop. The only way to turn it off is to permanently turn it off which destroys the alarm. Nest must be loving this because we are now buying another Nest to replace this pile of junk. June 14, 2015
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 Total Junk Goes off for no reason. Won't stop doing it. Not dependable. Have had two of them less than a year. July 30, 2015
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 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 1.0 out of 5.0 by Terrible Product Chirping 3 times in a row every 10 minutes at 0300 on a Saturday morning is not cool. Please review all products prior to making purchases. This is not worth the time spent to research it. I'll ensure my next purchase is better rated or for my family's safety we'll go old school. Changing the battery every 6 months is better.

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
