Plug-in Carbon Monoxide Detector with Digital Color Display CO Detector for CO Temperature Humidity 85dB Loud Alert Self

I’m really impressed with this plug-in carbon monoxide detector. Setup was incredibly easy—just plug it into any standard outlet and it starts working right away. It’s more than just a CO detector: the display clearly shows real-time carbon monoxide levels, temperature, and humidity, which is super useful for monitoring indoor air quality. The self-test feature is also reassuring and easy to use. Overall, this device is a great combination of safety, functionality, and convenience. Highly recommended! Read more

I had to refresh my old CO detectors and these worked great! Loved that they don’t need batteries AND how compact they are (based on the size of my old detectors). They plug into your outlet and work promptly. Bought 3 for me and my kids places. Read more

Really easy. Just plug it in. It's nice that it gives you temperature and humidity level too for a good price. Read more

The design is nice, alarm sound for testing seems good, plugged in, so not sure about battery option, instructions were good! Detection Accuracy - “Not sure” Hopefully, we never have to find out. But I guess we may never know. If it ever does go off, I’ll update the review. If it doesn’t go off, then well…it’s either doing its job or this review will remain unfinished forever… Read more

These work perfectly and do not take up the entire outlet! Easy to plug in and work immediately. I have one near our gas fireplace in the living room and one in our bedroom that has a gas fireplace. Read more

Affordable way to give this mom peace of mind! After unboxing I plugged it in downstairs in the basement where our ventless propane fireplace is at. We only use it when we're down there, but I wanted to ensure it is safe when we do. It's easy to read and has instructions that are very informative and answered any questions I had. Great and affordable buy!! Read more
