First Alert CO710 Carbon Monoxide Detector with 10-Year Battery and Digital Temperature Display , White

I bought this to use as a travel CO detector, as I visit many different hotels throughout each year. Having this with me will provide a little extra peace of mind, because there's no telling what quality of maintenance and repairs have been done with systems and equipment at a hotel that could emit CO. I chose this one because it has a temperature read-out on the LCD screen which I thought would be handy. I do wish the unit was slightly smaller so it takes up less space when traveling. It's roughly the size of an iPhone. I like it so far. But let's be honest - how could we really know how well a CO detector works?!

Got this to replace previous owner’s 10-yr detector. Only wiahed it was round like the previous so there wouldn’t be a weird round unpainted spot on wall where the previous folks painted around the detector. I ended up making a trim to make it look like a mount to cover up the previous unpainted round spot and put this right on top of the previous.i like that it has a thermometer on it.

This is awesome. I bring whenever we sleep elsewhere for added security. Perfect size

My furnace is on the fritz so hopefully it works so we don't die.

There are no 9V batteries to replace with this unit. It is rated to work for 10 years without a battery change. You will save a lot of time and money by not having to put in a new battery each year. In addition, it has a temperature display built in. This is very handy if, for example, you put this in a spare bedroom that is not heated all the time and you want to check the temperature.

Often when I am driving long distance via car, it's necessary for me to pull into rest stops occasionally to take naps, if not to sleep overnight. On those nights when it is very cold outside I will, by necessity, leave my engine and heater running to keep me comfortable inside the car (which means, to keep me from freezing to death).When I sleep in the car with the engine running I am extremely aware of the danger of possible carbon monoxide poisoning, which is an odorless and deadly gas in confined areas. I keep this carbon monoxide monitor in my car at all times, and if I nap in my car with the engine and heater running, I will just set this up on my dash to watch over me while I sleep. And the alarm, if it should be tripped due to the presence of carbon monoxide, is Extremely Loud! Keep in mind this monitor is basically meant for home use and is very loud for that reason, it is especially loud inside a car! But if CO2 should begin building up in my car while I'm sleeping, this thing is loud enough to wake the dead, so I will be able to exit the car to fresh air quickly before anything bad happens to me.I consider this an essential device for my car trips. Highly recommended for both home and car or RV travel use, this is a safety device that everyone should have.

We bought these for our rental properties. We actually ordered multiple times. Good quality, easy to install and affordable.

Bought multiple units. Very easy to use and vital for safety at home or when traveling
