Kidde Worry Free 10-Year Lithium Battery Carbon Monoxide Detector with Digital Display (2-pack) is rated 4.6 out of 5 by 260.
Rated 5 out of 5 by from Actual Exposure...It Works! I bought this unit 8 months ago after a potentially deadly exposure in our six unit apartment building. A few of our previous CO detectors in several of the apartments gave the dead battery signal instead of an alarm so no one was alerted. We ended up being evacuated by the fire department in the middle of the night and one person going to the hospital! I did a good deal of research, bought this unit and have felt much safer. Just last week we had another brief exposure as our gas water heater had a leak in the flue. There was not enough CO to set off the alarm, but the detector window showed 13 ppm, less than the 30 ppm to set off the alarm, but the fact that the detector worked as advertised, even if 13 ppm is not dangerous, is still very reassuring to me. I have recommended this product to all of my friends and family. The sealed 10 year battery is a real plus. I have it mounted at eye level in my kitchen, which is nearest to the boiler room and the enclosed garages. I can check and test it often and easily.

Rated 5 out of 5 by from The numeric read out is so much more helpful than a series of ear-piercing beeps that could mean ... The numeric read out is so much more helpful than a series of ear-piercing beeps that could mean low battery, emergency, or unit malfunction. While most units are only good for one year, at which time the battery and/or entire unit fail, this one is designed to last ten years. With the ten year battery, we won't be awakened in the middle of the night every year wondering if we heard four beeps or five, do we turn it off or evacuate? If this unit goes off any time in the next ten years, it shouldn't be the battery or unit malfunction, but the read out will clearly tell us what the Co2 level is so we'll know if there is an emergency.

Rated 5 out of 5 by from Super Simple Installation - Great peace of mind. This CO detector is a great find! I like the idea that it is self-contained and does not require any batteries for it's lifespan. After 10 years, it can be replaced by referencing the installed date or the unit is designed to alert the homeowner via alarm when the batteries have been depleted and has reached end of life. The unit is shipped with the mounting plate removed. Once the mounting plate is connected with the CO alarm, the batteries start. No worries with getting a unit that has been sitting on the shelves for a year. The alarm was easy to install. It can be used as a table-top alarm, but I installed it using the two supplied drywall anchors and screws near a bedroom door. Once it was connected to the backplate - it started up and it's been monitoring since then. The digital readout is also a nice feature on this unit. You can see status on recent readings, mine has been showing "0", which is good, since it was installed.

Following the enclosed instructions, they were easy to install. Live in a single story ranch home, with about 1350 square feet of living space. I feel that these two detectors will adequately protect our home.

You don't have to worry about changing battery or plug into your outlet. It have a flash to let you know it's working and keep track of the carbon monoxide level, if you have any. I would recommend this product to purchase.
