    Rated 3.4 out of 5★ by 10reviewers.
    Rated 5 out of 5★ by Great deal! Two of these come, with batteries and mounting hardware, for the price of just one sensor at the local hardware store. We have a two-story home so we definitely wanted two of these. The CO sensors are now required by law in California, but it's just a good idea to have them, anyway, especially since both our gas heater and gas water heater are located inside the home. 08/19/2011
    Rated 1 out of 5★ by HUGE design flaw regarding battery I'm actually shocked that this carbon monoxide alarm is on the market. The design of the battery compartment does not allow the battery to make contact with the sensors rendering the thing completely useless. Additionally, the description mentions that it takes two AA batteries. The 2-pack that I was shipped takes 9V batteries. Is this an old model? Another review from 7/24/13 has the same issue., please take note!! 01/24/2014
    Rated 1 out of 5★ by cheap and stupid cheap price stupid design and stupid install directions. battery hard to access. battery hard to snap in. template installation guide is wrong. manufacturer is aware of wrong install instructions which causes more holes in your wall, and does nothing about it. cheap price stupid design. 12/24/2013
    Rated 5 out of 5★ by I hope to never need this detector but is is highly rated & it is easy to place within the home. 12/11/2012
    Rated 1 out of 5★ by Design issue, doesn't work. First, the battery opening cover is hard to open and close, 2nd. the 9V battery case opening is too big, after inserting the battery, there is about 1cm gap left between battery and the wall. 9V battery's 2 head will not touch the battery snap. How this will work? return it next day. 07/24/2013
