CUSTOMER REVIEWS

Rated 4.2 out of 5 by 124 reviewers.
Rated 5.0 out of 5.0 by Great basic smoke alarm. This is a great basic smoke alarm at the right price. Easy installation and looks good. I have had no nuisance alarms. This alarm is interconnected to all the alarms in my house. If one alarm is activated, they all alarm. November 18, 2013
Rated 4.0 out of 5.0 by Good product Good product but keeps going off if it is near a cooking area. It also was chirping every 30 seconds and it was chirping at midnight. March 7, 2015
Rated 5.0 out of 5.0 by Excellent purchase The installation was non-sense. Just remove the old wiring harness (from the previous or old detector) and replace with the new one. Replace the mounting plate and install the new detector. Finally remove the battery protection tab, close the battery compartment and press the test button. As simple and quick as that. The battery backup feature is a nice addition tho the detector, so you still has protection during a power outage (you may be using candles to light your house). I bought four. Excellent purchase.

Rated 1.0 out of 5.0 by Buy a better Alarm Bought two of these alarms to replace the orginal detectors that were 30 years old. After only two years of use, one of the alarms started late night and early am false alarms. Following the instructions the alarm was blown out with compressed air on three different occasions. The alarm STILL gives off false alarms. It's made in China and recommended to be replaced every ten years. I only got two years before it failed. May 6, 2015
Rated 1.0 out of 5.0 by 2 of my 6 i-4168 firex alarms failed within one year I installed 6 of these firex smoke alarms and two have failed within 1 year. The defective alarms started chirping about every 2 minutes. The batteries were tested good and there was no dust present. November 7, 2014
Rated 5.0 out of 5.0 by Great smoke alarm Great looking and fairly easy to install. Removed old alarms and replaced with these alarms July 28, 2015
Rated 4.0 out of 5.0 by Smoke alarm with Battery Backup The smoke alarm was easy to install and works fine. Passed the home inspection with no problem. July 27, 2015
Rated 1.0 out of 5.0 by Not Reliable Even When New I replaced two seven-year-old First Alert alarms with these KIDDE Firex smoke alarms I4618. Six hours after the install we had our first "FALSE" alarm. It was a cool (70 degrees) summer night with low humidity. We HUSHED the alarms and then about twenty minutes later it happened again. Took them both down and will return them tomorrow and try something else. These alarms are not reliable. After reading reviews on the HD website and Amazon, it seems lots of folks are having this same issue. July 7, 2015
