The Good, the Bad, and the Ugly
This item was to replace the old ones that were already installed in my home.The GoodThese were very easy to install, but then again I already had other ones wired. The fit in the same receptacle, and seem to be good quality. Battery life doesn't really apply, since they are hardwired in my case.The BadThey work very well, now when I 'try' to cook and the kitchen fills with smoke they go off like crazy. The alarm is definitely loud enough.The UglyThe wiring in my house was actually not up to code. When I installed the final one I couldn't figure out why it was not behaving correctly. I am actually very glad I bought this multi pack because if I hadn't I never would have found the mistake the previous home owner had made when he wired the basement.

Great Smoke Detector Replacement
I purchased another brand, which I liked, but the unit(s) failed at install. So, I tried Kidde. The directions were good, but the print was small. Also, hardware likes screws and wire nuts were not included. I turned off house breaker and tested house wires for power. Then, reading the directions again and watching a Kidde install video, I installed 10 of these units in my house. There was a slight learning curve. But, after install, I applied power again, they all worked perfectly without a single chirp! Testing was quick and easy. I recommend buying the ten-year battery model as the AA model batteries must be replaced once a year. The ten-year battery models were available if I wanted to wait another week for delivery. Kidde claims these alarms are “UL listed” which I need to meet my city building code. These were a great smoke detector replacement.

Installation
The connector to the house wiring has been changed from previous models (mine were 10 yearsold), making the installation a bit longer.

Easy Install
The media could not be loaded. Very easy to install. Picks up smoke nicely. I blew out a 3-wick candle and it picked up the smoke.
