FIRST ALERTCO710 Carbon Monoxide Detector with 10-Year Battery and Digital Temperature Display , White

I wanted carbon monoxide detectors with a digital display and the built-in 10 year battery and these are perfect. I've purchased them before and had no issues with them. I bought a couple more for other areas of the house because they are so convenient. Place them and they'll do their job. Very convenient.

For the last 5 years, I have had a First Alert CO monitor near my gas fireplace. Nice to have the temperature showing in large display as well. When the alarm sounded to indicate my monitor was at the end of its life, I looked for a replacement. The upgraded/repackaged First Alert CO monitor on Amazon was the best choice for me; I'm still able to see the temperature in large numbers, with confidence that this monitor will warn me if we have a CO issue in my home.

I love that it can sit on a table top and it’s small so it’s not an eyesore. The ten year built in battery means no batteries to replace.

I moved into a very old house with very thick concrete walls, making drilling frustrating. The home I purchased came with the previous model of this detector. I saw mixed messages about whether the screws were aligned the same as the old model. Unfortunately, I found out that the screws are off by just the tiniest amount and won't fit on the old ones. It's kind of maddening that First Alert did this. I would love to just know why. Why frustrate customers like this?I am still using the new model, but I have it sitting on a shelf. This model of detector is great for those of us with old homes who can't drill into the wall. I like the unit itself. It stands on a shelf easily and it's unobtrusive. I like that it has the air temperature displayed and it has an overall modern look.I still recommend this item. Just don't buy this unit thinking that you can use the screws from the old model.

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.

Carbon monoxide alarms have protected my family many times when below deck on a boat. (fumes would sometimes blow into the cabin and we couldn't smell it but the alarm knew.) We keep these in several rooms of our home and sometimes travel with them. Most recently, I invested in another one to send with my kid to college. Even though rental units and dorms are required to have a carbon monoxide detector, I don't know that they are maintained or updated when other people are responsible for upkeep. It is a tiny price to protect my family and well worth the piece of mind. This model doesn't take up much space. It doesn't need an outlet and is portable. We just set it on a shelf or dresser. It comes with a 5 year battery. I like that it serves a dual purpose of listing the room temperature too. Of course the primary reason we buy these is safety. Sadly, there are too many cases of people losing their lives or being hospitalized because of carbon monoxide poisoning in dorms, apartments, workshops, etc... Just be sure your family knows to open windows and evacuate quickly if the alarm goes off. Highly recommend.

4days after I received this it went off. Yep I had CO in my home. It was the water heater! So grateful!
