Title: Good price for a trusted name brand.
Review: Just had a whole house generator installed. Local code requires CO detectors in all bedrooms if you have a generator. These plug in to a wall receptacle so installation is easy. The two AA back-up batteries are included. The alarm is loud & piercing. They are well made which is typical of other First Alert devices that I have.

Title: Tested fine right out of the box. Comes with a battery. Good Brand Name.
Review: The inclusion of a 9V battery right out of the box is a thoughtful touch. It gives me peace of mind knowing that the detector is ready to go, and the added battery backup ensures continuous protection even during power outages.I tested the detector when it arrived, and everything checked out. The ease of setup and the immediate functionality straight out of the box impressed me. The clear instructions provided made the installation process a breeze.As a consumer, the First Alert brand has always been synonymous with reliability and trust. This CO detector is no exception. It reinforces my confidence in the brand, and I appreciate the commitment to delivering high-quality products that prioritize safety... at a reasonable price.The white design seamlessly blends with my home decor, making it unobtrusive. The compact size ensures it doesn't take up much space.In summary, the First Alert CO605 Carbon Monoxide Detector is a stellar product that offers peace of mind, reliability, and ease of use. I highly recommend it to anyone in need of a top-notch carbon monoxide detector. Five stars – well deserved!

Title: Good units, I just don't like the red light in place of a green.
Review: I bought two of these to replace some older CO detectors which were nearing the end of their lives. I haven't tested these units for accuracy but I have no reason to believe they will not work. Installation was simple. Just put the batteries in and plug in to the wall. I gave 4 stars instead of 5 because I don't like that the "everything is ok" status is a solid red light. Red light = bad! in our society. It would be much more comforting to look at these units and see a solid green light when all is well, especially when that's how my smoke detector works. When you're getting these set up, I'd recommend first noting the dates of manufacture printed on the back to get an idea of when they're going to need to be replaced. Both units I bought were less than a year old. Also, test that battery that comes with the unit to make sure it's good. Test the unit when its unplugged and when its plugged in to make sure it beeps.

Title: Manufactured Dates
Review: Just received these tonight. They came well packaged, new, no tampering. Each unit came with it's own back up battery. Directions / instruction booklet is thorough, though print is very small, even for someone who's (relatively) young yet.I tested each unit once I installed the barriers & they functioned as expected. They are pretty loud, which is good. Once plugged in the red light glows steadily which is what it's supposed to do. Some people mentioned it being really bright, they aren't.Lastly, please note that the date on the back of the unit is NOT the expiration date! This is the manufactured date (see my photos).I'll update if one of them starts acting up, otherwise I feel good about these & would recommend.
