Kidde Carbon Monoxide Detector, Propane, Natural, Methane, & Explosive Gas Alarm, Plug-In Wall with 9-Volt Battery Backup, Digital LED Display

For the people leaving negative reviews regarding this detector NOT working... I'm not going to say you're wrong, because you may have just gotten a bad one per chance, but I will say, after reading your reviews it prompted me to test this immediately and directly as you stated, in front of the stove with the gas on, and I must say here, the one I received works fantastic, as it went off like 2 seconds after placing it in front of to the gas stove that I blew out to test just the gas fumes only, and sure enough, I must say... you can't speak for everyone when it comes to high volume sold products on amazon. You may have received a defective detector, and I invite anyone to do the same. These are no good if they don't work right. Test immediately when you receive to make sure! Couldn't be happier with the peace of mind this product gives my family and I. Would highly recommend. I've learned to not always go by negative reviews especially when the good outweighs the bad.

I could not find these locally. They work and test well on the unit. I’ve had them for years and needed a replacement. Plug in easy installation. They have never been tested in an actual detection as it is a bit easier to “live test” a smoke alarm but, I don’t have a wired system and this makes me feel more secure.

I'm about to wax poetic about the "Safety Siren Pro Series 1000" (or whatever demonic device this is). Let's be clear, this thing detects carbon monoxide like a bloodhound sniffs out a dropped hotdog at a picnic. No complaints there. If there's a rogue molecule of CO within a five-mile radius, this thing will know. It's like having a tiny, hyper-vigilant, gas-detecting chihuahua with a PhD in atmospheric chemistry.But, and this is a BIG but, when those batteries start to wane, oh. sweet merciful heavens... it's like a tiny, metal-clad demon has taken up residence in my home. The beeping... the BEEPING... isn't your standard, "Oh, batteries are low, please replace me" chirp. No, this is a sustained, high-pitched, soul-rending wail that sounds like a chorus of dying smoke detectors harmonizing with a dentist's drill.It starts subtly, a little "beep" here, a little "beep" there. You think, "Oh, I'll change them tomorrow." WRONG. You've just signed a pact with auditory torment. Within hours, it evolves into a relentless, rhythmic pulse of pure, unadulterated annoyance. My cat now hides under the sofa, my plants have visibly wilted, and I've started having flashbacks to that scene in Reefer Madness where the guy leaps out the window, convinced he's being chased by jazz demons.I swear, this thing is less a safety device and more a psychological warfare instrument. It's so effective at alerting you to low batteries that you'll replace them out of sheer, unbridled terror. You'll be sprinting to the store, batteries clutched in your trembling hands, like you're carrying the antidote to the apocalypse.Five stars for gas detection, minus a million for auditory assault. If you value your sanity, buy this thing, but keep a fresh pack of batteries on standby, and maybe invest in some industrial-grade earplugs. You've been warned.

I have a piece of mind that now that I have Device in my home. I think this is a necessity for everyone to have highly recommend it.

It works and I like that it has a cable so that I can install it on the ceiling. I wish the CO sensor was more sensitive. I tested it with smoke from a burning piece of wood. It does fires the alarm eventually, but significantly later than my other CO detector.

It absolutely detected a gas leak from my stovetop before I did.I am definitely recommending this potentially life-saving device.

I bought one for each of our 3 floors to detect propane gas. I also bought 3 for my daughter's house who heats her house with natural gas. They are so easy to just plug in. Very easy to see the readout.

Producto de buena calidad. Funciona muy bien.
