It is important to have a working smoke detector and carbon monoxide detector in your home and at work. I am pleased to have these in my home and the protection they offer me and my family when something unexpected may happen.

I purchased these when our 15 year-old smoke alarm died. My husband was impressed because it was a two-pack for a decent deal and it has a carbon monoxide detector. It is smaller than other ones but that wasn't a big deal. It flashes a blue light maybe every 60 seconds or so ... not a big deal. We have one in our bedroom over our bed and notice it at night but it does not keep us up or affect our sleep. We are glad we bought these!

We have hard-wired detectors in our house but I thought "what happens if the power is out?" Ordered these as a back up and they are very nice/good units. Love that they "show me" a digital display and have "test" modes. So glad we purchased this package of 2! Putting one in our basement by our furnace and the 2nd heading up the stairway to our living area. When tested, I could hear them upstairs!!! Definitely recommend these.

Easy to install. Is smaller that older models, so if you look up you can see the old ceiling vs any updates made. Not a huge issue.Tested product and works well, loud and solid. Not 100% sure it will continue to do so in actual event, not familiar with this brand, 1st time buyer.
