The perfect replacement smoke alarm

Would Recommend

The smoke alarms in my house were the originals when the house was built in 2006, really?? I was shocked that the previous owners were clueless that alarms need to be replaced at least every 10 years. These First Alert smoke alarms were the perfect replacement as the plug AND the ceiling mounting plate were the same so all I had to do was plug the new alarm in. Brilliant!! :-)

No other options

Would Not Recommend

I was unable to locate any other options in the store, and had to purchase a wired version. When I checked out, the receipt I was given was not mine - I will still attempt to return it this weekend.

Very easy to install!

Would Recommend

Recently replaced all of the smoke detectors in my house with these and am very happy. They were very easy to install and are working great. My old ones were original to my 20 yr old house and yet the connectors were still a match!

Great replacement for my 20 year old detector

Would Recommend

Replaced 6 detectors in my home with these. Installation was a breeze and they work great. The included 3 different wire adapters that cover most wiring configurations you will see these days. A nice bonus was the 9V battery included with each unit. Well priced at $29 in my opinion. Hopefully these last several years (aside from the batteries).
