December 12, 2017I wanted to replace the detector in my furnace area with a carbon monoxide alarm and this was a great way to get this done. It is working great and also easy to install.

Bought two of these to replace old ones. Design seems great and actually fit using the same anchors and screws from other brand I was replacing. Glad our dog won't have to hear low battery warning any longer!

Like the convenience of having carbon monoxide monitored as well as fire and smoke in the same unit with the sealed long lasting battery.

I bought several USI products for my own home -- including these -- about a month ago. Attractive and easy to install. I bought two more for my parents, and I am about to buy several additional items.

Oversize base-plate is excellent. No problem covering all signs of old installation. Easy to temporarily remove when time to paint the ceiling.
