Just purchased 2nd one of these. Very good units, BUT: 1) Packaging is ridiculously difficult to open, and 2)if alarm sounds, pushing the silencer button does not always silence the unit.  see moreof Northstar's review

    I purchased and installed 3 of these in different parts of the house. After about 4 months one of them alarmed. No smoke, steam, nothing apparent. The batteries are strong as per battery tester. Figured it was a fluke. However, about 1.5 months later the same thing happened. The other 2 are be...  see moreof pete445's review

      I agree with another reviewer that these are, indeed good units, and also that pushing the "silence" button does not always silence the unit immediately. But that's just small potatoes as overall a well-respected device that does as it's intended to do. Also, if you have more than one of these units...  see moreof Ardo's review

        I've only had this alarm in my home for about a week. At this point, it seems to be working well, but it's hard to tell this early in the game. Here's why I gave it a 4 instead of a 5: I had previously installed a First Alert alarm in my hallway. I was hoping that this new one would match the mount ...  see moreof Rexburger's review

          We purchased 5 of these to update our 1960s house to current code (where you should have alarms in every bedroom, and at least one per floor). After a lot of research, I settled on this model because of the 10-year life (some are only 3), dual sensor (both photoelectric and ionization, which sense t...  see moreof LittleLoomis's review
