Amazing product works good
Good alarm works well. It is pretty loud but it is supposed to so it will wake you up at night. Very easy to use all you have to do is plug into a wall. Easy to mount. Easy to read. I felt so much safer after buying this. Would 100% recommend.

Seven years
Just bought two more of these. The first one I got lasted exactly 7 years and three months. Well worth 25 bucks for seven years protection! Never had to replace the battery end never had any false alarms, until the end-of-life (5 chirps)

Working Good
Working Good so far. Quality is good, and it is easy to use. The position of the plug makes it mount flush against my wall. Carbon monoxide is very dangerous, so these are a must have for any household.

Came fast and easy to plug in, but how is anyone suppose to know if it works??
Needed it quickly and Amazon came through. Effectiveness? Honestly, the only way to tell if it functions is if you have a CO issue, right? It does allow you to test the alarm, but not its ability to detect CO. Idea: include a sample of CO (you can buy this on Amazon but it’s ridiculously costly) so that it is doing what it is supposed to do.
A**!
So glad I had this!
Today, I had a carbon monoxide leak coming from my basement which is three levels down from where I had this carbon monoxide detector plugged in. This thing perform amazingly!! It detected a leak coming from my basement. All the way up stairs into my bedroom! I have wired detectors too. But I was so impressed with this plug in and the distance that it was able to detect the carbon monoxide! What a life saver! I am buying two more as back ups. If I could give it 10 stars I would. I was not compensated nor am I recieving any rewards/perks etc. This is my own personal experience with the product. And this all happened today, 3/31/25. I am going to buy this brand from now on. I can not state enough how grateful I am for this little plug in backup. Buy it!!!
