  • Excellent choice
Size: 5-Pack

  • Great price and simple installation!
Size: 6-Pack
Easy installation and work well. Purchased these for a house we were selling where new city codes required more detectors. Used these to replace old ones and install in places now needed. The install was simple and quick. Testing is easy and they are loud.

  • Everything included except mounting equipment.
Size: 6-Pack
Reasonably prices combo co and smoke detector. You will need a drill to place this into your walls. Batteries included and quick set up. This is not for hard wire.

  • Make sure you're sending what you listed & I purchased, please & thank you
Size: 6-Pack
Arrived fast and a great value. Got them today and not installed yet. I'm deducting a star for SHORTING me (others are having this issue too). I purchased a package of 6. It should have come with 6 packages of mounting screws and 6 packages of batteries (3 in each package because each unit takes 3 batteries). It came with all of the mounting screws, but SHORTED ME HALF OF THE BATTERIES (I got 3 packages, not 6). That's irritating - even if they aren't long-life batteries. Don't advertise it if you're not going to deliver it. I'll test the units and will update my feedback if they don't meet my expectations (of a unit that works as intended). ... show more
