A necessity for every home

Very easy (and quick!) to install. Had to replace the previous smoke detector, as it ran its course and had to be retired. This new one was the right price, a bit bigger than the old detector, but we're glad to continue to keep the protection in place at home.

No more 9V batteries!

I had no idea that smoke alarms now have a 10-yr. built-in battery that needs NO replacing! No more 9V batteries! It's easy to install, has a place to write when installed and when to replace in 10 yrs. I love that I don't have to worry about it for 10 yrs., at which time you replace the entire unit. I definitely recommend it!
