What we love

Some folks aren’t aware that smoke and carbon monoxide detectors have a 7- to 10-year lifespan. So if you think the ones in your home may be approaching or past that timeframe, now is a great time to get them replaced. Up to 12 of these can be paired using built-in RF technology. If you plan to buy more than one, purchase one at a time and the on-page coupon should keep reappearing.
