• Combo smoke detector/carbon monoxide alarm detects two threats
  • Electrochemical CO sensor alerts you to carbon monoxide danger
  • Photoelectric sensor detects smoke while minimizing false alarms
  • Battery-operated unit installs quickly and easily without an electrician
  • A single button tests the unit or silences the alarm. Low battery signal mute, quiets low battery signal for up to 8 hours

Very good so far. It doesn’t go off when minor cooking issues (the last one always went off) so that’s hopefully good for skipping false alarms...or it doesn’t work at all (haha) - not sure on that. But at this point would highly recommend.

tested by burning paper and they worked. Not hard wired

Works great! Love the combo of smoke detector and carbon monoxide detector. My father (a retired firefighter) recommended the battery version over a hardwired one. In a power outage they will continue to work

This is an incredible fire caution, with consolidated smoke and CO finder. Simple to introduce, has area recognizable proof and voice alarm so it reveals to you the kind of caution (smoke or CO) and the area. Really gives the most ideal security.

It was anything but difficult to introduce and is exceptionally minimal. it is exceptionally pleasant to have the mix in one little gadget which isn't extremely noticable in view of the little plan. Awesome find!

They were very easy to install work very good thanks for the great product

We bought these for our new house and needed one for each of our above ground floors. They have worked as advertised and was simple to install.

I was wary to purchase given lower price range and no reviews, but all in all I am impressed: -2Pack: Clean, Small, Affordable, Functions as expected. -Easy to use, with no issues seen on first testing or installation. -BE AWARE of minor false-advertisement: 1. This product comes with and uses 9V battery packs (AA advertised) 2. The alarm is a loud beep, as loud as any other alarm I've used (not a "horn" as advertised)

Works exceptionally well and took under 5 minutes to introduce...

This item is a smoke alarm and carbon monoxide alarm all in one. Inexpensive and very easy to install. Even comes with batteries.
