Works exactly as expected! The display is clear, and it’s easy to install. Tested it, and both smoke and CO detection work well. The alarm is loud enough to hear from another room. Battery life seems solid so far.

Fairly compact compared to other typical smoke/carbon monoxide detectors. The functionality of being a dual detector is nice. The alarm test sound wasn't exceptionally loud, it's loud but I'd personally like it blaring. In the event of an actual emergency, you don't want to wonder if you'll hear your basement detector go off while you're sleeping. The price point of this detector is very competitive relative to similarly equipped devices on Amazon.The LCD is neat, but seems an unnecessary feature and possible battery drain. I can't really imagine a situation where seeing undesirable co2 levels would be useful... wouldn't the alarm be going off? I'm not sticking around to read the display while I pass out...lol.Only one actual complaint; the included batteries are extremely poor quality and fragile. I actually squished one slightly (see pictures) while removing the plastic wrapping. Ultimately, I didn't trust these batteries and threw in a couple of my own lithium AAs, also figuring they'll probably last the life of the detector anyway.

Came quickly. Easy to install. Has 3 years service life so not going to have to think about it for a while. Comes with batteries pre-installed as well. Just needed to attach it to the ceiling and good to go. Also it's nice to have a digital screen for a change

The fact that it detects both smoke and carbon monoxide provides me with added peace of mind, knowing that my home and loved ones are better protected.I love that it comes with batteries, making it truly plug-and-play. The display is clear and easy to read, providing vital information at a glance.The combination of smoke and carbon monoxide detection in one device is incredibly convenient and space-saving. The fact that I can rely on one device to alert me to potential dangers is a huge plus.

These came in a 2 pack. Small so not as noticeable. They have a high pitch so loud enough to alert ya. Batteries included just take them out to remove plastic from batteries for shipping. Easily to hang. Great value.
