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

Simple to install, works extremely well and the size fits almost anywhere. If something saves your life, is it a good value for the money, you bet it is! Peace of mind enough to move into a place without Carbon Monoxide threat. It's a bonus that it's also a room thermometer.

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

We never travel without this carbon monoxide detector! Most places we stay don’t have one, so we always bring our own. On our Leopard 40 catamaran, we keep one in every cabin plus the salon and galley, and we also take one along when staying in Airbnb or Vrbo rentals.The one time we didn’t bring it was while hiking Acatenango in Guatemala. After a 7-hour climb to base camp, we were freezing and exhausted when our guide lit a fire. Smoke filled the tiny hut and we woke up with splitting headaches -classic carbon monoxide exposure. That scary moment taught us a lesson: no matter where we go, even up a mountain, this detector comes with us.The battery lasts a long time, the digital temperature display is a great bonus, and the alarm is loud enough to wake you immediately. Durable, reliable, and truly a must have for safety at home, on a boat, or while traveling. Highly recommend!

this is a good replacement detector.. I would’ve given five stars, except as others mentioned. The mounting holes are not the same as older models from the same brand.

I like that this monitor is lightweight, has a backlight to view at night, and is loud enough to wake me wherever I am in the house. With it being compact and sturdy, with a 10-year battery, I bought a second one to take with me for safety when traveling.

I love this CO detector and saw it in action yesterday when it loudly beeped to warn me of dangerous levels of CO in my home. This winter I decided to use my fireplace and accidentally didn’t open the fuel hatch in the chimney. Completely my fault but within 5mins of me lighting the log on fire the alarm beeped warning me of CO in my house even before smoke started wafting. Thankfully, no damage was done and no one was hurt. I was able to very swiftly turn off all air conditioning, open doors to let the chill air in and extinguished the barely started fire. I am so thankful for this product and urge everyone to have one installed in their homes in addition to a fire alarm. The product also shows the current levels and you can monitor that as well. The design is sleek and is easy to install and use.

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?!

The first one expired...so got a replacement - very happy with this little thing, love that it is easily portable from room to room
