We needed to replace all our smoke alarms due to their age. These were a good brand, good price. Easy to install. No complaints.

One of my rental properties had this hard-wired smoke/CO2 detector that beeped and announced "low battery" every minute, even though it was plugged in and I had replaced the battery a few times. Rather than figuring out how to possibly repair it, I found this $17 hard-wired smoke detector (no CO2 detector is needed at this property). Kiddie provides multiple connectors, and one fits perfectly into the hard-wired connector plug in the ceiling. I couldn't use the base on the previous detector for this new detector (even though it's the same brand). I knocked out the correct holes in the new base (which was a PITA and why I dropped a star on the rating). All in all, a quick install. It works and it set me back less than $20. I recommend it.

The Kidde Smoke Detector is a type of smoke alarm designed for residential use. It is hardwired, meaning it is connected directly to the home's electrical system, and it is designed to detect smoke and alert residents to the presence of a fire. This smoke detector is equipped with a 9-volt battery backup that provides protection even during power outages. It also features a test button that allows users to easily check the unit's battery and alarm function.Positives:Hardwired design ensures a reliable connection to the electrical systemEquipped with a 9-volt battery backup for protection during power outagesTest button allows for easy testing of the unit's battery and alarm functionAffordableEasy to installNegatives:Some people may find that the alarm is too sensitiveOverall, the Kidde Smoke Detector is a good option for those looking for a reliable and easy-to-install smoke alarm for their home. The hardwired design ensures a reliable connection to the electrical system, and the 9-volt battery backup provides protection during power outages. However, some people may find that the alarm is too sensitive, not very loud, not very durable and not very reliable. I would rate this product 3.5 out of 5 stars.

The smoke detectors were easily fitted and have worked flawlessly so far. Could not be happier.

easy to install this hard wire smoke detector. directions are clear enough for those that don't have electrical experience.

Very easy install when replacing same brand, even over 20 years later. (Embarrassed to admit that I never knew you needed to replace smoke detectors every 10 years or less). I didn’t need to redo wiring or anything. I used a screwdriver, and it took me maybe 20-25 minutes to replace 6. Connected perfectly, beeped to indicate it received power, the end. The hardest part was breaking out the little plastic piece that aligned with where the screws needed to go. Some popped out relatively easily. Some I felt like I needed a hammer and chisel to get it off. The date of install sticker is a nice touch. For the price, it was a no brainer. I would have liked if these had the battery door on the outside, but I know they make that version for more money.

These were a perfect replacement for the whole house since they all needed to be replaced when I moved in (all were expired by 5+ years). While they can be sensitive, they work and work well.
