Outstanding Product
Clear start process and use of the CO detector. This is my second order with this product. Battery lasts 10 years as advertised.

It's a replacement CO detector. Buy it if you need it.
The CO detector is the pinnacle of the "better to have it and not need it" type of item. I had a Kidde alarm in my basement that started alarming end-of-life - manufactured in 2014, so dang near got 12 years out of it. Favorite thing about these is that they don't change the spacing or anything silly of the wall bracket, so it's as simple as popping the old bracket off the wall, popping the new one on, and finally, pop the detector onto the bracket to start it up. Hopefully good for another 10-12 years of protection. Thanks Kidde.

I trust Kidde
This is a brand I trust. I use it in my home and have never had an issue with malfunction. When my old battery-powered C02 detectors died out I replaced them with these. I appreciate the 10-year battery life. Makes the hassle of trying to remember what was replaced annually. My husband lost his sense of smell for the most part and I want to make sure that all of the detectors, smoke or otherwise, work. Easy to install, smaller design. Just remember to check the instructions regarding placement and label the date you installed it for easy reference.

Great carbon monoxide monitor - clear readout and alarm
Great carbon monoxide MONITOR. It both detects CO and gives you a PPM reading. You can mount it on the wall or just place it on the hearth above the fireplace. Good to go

It works
I bought this to replace the exact same one i have. The reason being because the one I have was a lifesaver. It went off 1st time ever registered 55 and fire dept narrowed it down to tankless water heater area and a plumber noticed outside vent had a flapper valve in it. Tankless vent prior to having siding replaced was not reinstalled by the siding people but replaced with a different type vent. Not enough airflow out. Carbon monoxide truly is a silent killer and this one worked when it needed to. Fire department recommended replacing it because once they go off it's a good idea to replace same as you would do with a smoke alarm. I have had original for almost 4 yrs now.
