Nice Unit!

Would Recommend

I got tired of First Alert failures so I switched to this and am glad I did. Easy install and so far so good. One of those things you hope you never need but great to have.

Amazing 10-year battery

Would Recommend

Set it and forget it with this ten year battery. Just make sure you’re paying attention to which detector you’re buying. It’s easy to pick up just a smoke detector when what you actually want is smoke and carbon monoxide.
