  • Easy Brezzy Install
Color: white-90504
I purchased these combos for a multi-family building, and they were easy to install. Thus far, no issues, I cannot comment on the battery's life cycle because they have only been up for less than a month. Great price.

  • Get cha one!
Color: white-90504
OMG! There is no need for a long, detailed description of the CO & Smoke alarm. I placed batteries batteries in and took all 4 alarms to my garage. Not only did the CO alarm go off, but that smoke alarm went off as well from the paper I lit. Purchase and test for yourself these are a must.Great buy.

  • Half of them defective
Color: white-90504
2 out of the 4 alarms I received do not work. I tried different batteries for testing and they displayed Eff and continuously screeched. The other 2 seemed to work when testing. As a first time homeowner of a house that needs a lot of work, the last thing I need is the hassle of returning this product for an exchange. I also dont trust the next package of them would work either. ... show more
