Comments

A. Farr: These were very east to install!

United States on Dec 09, 2023

Tim King: Bought this as a replacement. Great value and gives us that sense of security for both fires and CO2. Good quality and just what we needed.

United States on Sep 17, 2023

Sean H: Time to replace my old ones so I bought this for the value, installing process and supposed long battery life .

United States on Sep 05, 2023

LeAnn H.: I bought this for our RV. It was easy to install and had worked fine for the 2 months we have used the trailer. It is sensitive and has gone off while cooking bacon, but I would rather have that than not.

United States on Jul 18, 2023

Janet Succamore: Bought for obvious safety, works when something has happened, when cooking.

United Kingdom on Jul 02, 2023

Nicholas: I bought one of these because it's now bizarrely difficult to find a smoke/CO2 detector that uses a 9V battery and doesn't have a built in permanent battery, the latter of which with I've had nothing but bad experiences with. This new one seems to work okay, but the design/construction is a little wonky, but I guess it's fine.
