Works great. Its a basic smoke detector. Does go out after about 5 years. That is how long the last one lasted. This is replacing an original one. They work great and are very loud.

The smoke detectors were a disappointment. They included batteries, but they were not 10 year batteries which are required in my state. The alarms had 7 year warranties, so I assume 7 year batteries.

The back was very difficult to get off, at least for my Senior self. Won't actually know how works unless, God forbid, I have a fire.

These are horrible. I have about 6 of them and had to take all down because they constantly go off for no reason.

Response from Kidde ExpertNov 13, 2023
Hello. If you have issues with our alarms again, please call us at 1-800-880-6788 while onsite with the alarms before you replace them. We do stand behind our products and we are happy to troubleshoot and figure out what is going on and get an issue resolved. False alarms are most commonly caused by something interfering with the sensor. To clean the alarm, hold the unit by its edge and thoroughly blow through the gap on the side of the unit with compressed air (like keyboard cleaner). We recommend cleaning out all of your smoke alarms at least every 6 months to a year and at this point we would recommend cleaning out all of your other alarms as well as a preventative. Some of your alarms may be in one the locations to avoid listed in the owner's manuals. This would especially include alarms being installed within 3 ft (.9m) of a forced air supply ducts used for heating or cooling, ceiling or whole house ventilating fans, or other high air flow areas. We recommend that alarms not be installed near vents, flues, chimneys, or fans. We recommend that alarms not be installed near doors or windows near areas directly exposed to the weather. We strongly recommend not to install these alarms in garages, attics, and crawl spaces as you will get temperatures, dust, insects, and chemicals that can cause nuisance alarms. Try cleaning out the alarms. If you have the issue again, find the alarm setting off all of the others and call us with that alarm in hand at 1-800-880-6788 so we can get this resolved for you.
