CUSTOMER REVIEWS

Rated 4.0 out of 5 by 49 reviewers.
Rated 4.0 out of 5.0 by Kitchen fume resistant The mounting ring on this unit is strange, only about the size of a USA 50 cent piece. (See attached photo of similar unit with same mounting system.) 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. To activate the unit, you have to give it a hard twist on the mounting system, and it felt like I was going to rip it right off the ceiling. I really would prefer a different, more traditional mounting system. Mounting issues aside, this unit is full of features. CO detection and kitchen fume resistance were why I got this unit. We have wired detectors in our house of ionization type, so the fact that this unit is photo-electric is a perfect complement for our kitchen area. The unit has passed our "broiler test" with flying colors. No more fanning the fumes from the detector. It can handle a few broiler fumes, no problem. I can't speak for the CO element. That's something I hope to never test. It is comforting to have as a second CO unit in our house. July 6, 2014
Rated 5.0 out of 5.0 by No Battey-change smoke detector Very unique and at the same time advantageous. What is better than a smoke detector that has a battery that lasts 10 years, also the time that the sensor lasts in any detector. Ingenious. I placed one directly outside the furnace room, outside my son's bedroom. June 17, 2014
Rated 1.0 out of 5.0 by DO NOT BUY!!! We bought two of these detectors only 8 weeks ago. We had one of the alarms start beeping indicating there was a Smoke Alarm. However, there was NO smoke and NO fire. The Hush button did not work so the alarm continued to go off for the next 1 1/2 hours. Finally, we had to turn the OFF screw which means the detector is no longer useable! It is suddenly a paperweight! This caused me to look at the second detector. It was then I noticed that one suddenly doesn't work! You have to be kidding me! After looking at others reviews on line this is par for the course for this make/model. What kind of company sells garbage like this when families are expecting this product to protect their lives? We will never buy another product from Kiddie. Second, we feel let down by Home Depot for selling such junk! September 5, 2014
Rated 1.0 out of 5.0 by Failed After four months the alarm went off at 2AM. There was no fire and the hush button didnt work. Turned off screw on back to silence and now detector is useless. October 9, 2014
Rated 1.0 out of 5.0 by 'Had to dispose after one alarm! 'Wasted $ !!!!!!!!! The alarm was easy to install. It alerted us when our coal stove gave off a slight bit of smoke, and then it had to be disposed! What an awful design, to not be able to use again!!!!!!! November 20, 2014
