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

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.

Good: The perfect alarm for a detached garage. Detects smoke, CO, natural gas AND propane, with a display on the front that shows levels of same even when they're too low to trigger the alarm. Alarm is loud enough to hear in the house, eight feet away. Plugs directly into an outlet, or you can detach the power supply and mount the alarm away from the outlet. Pricey, but you get a lot for that price. Bad: Not the most stylish unit. But, in the garage, who cares? At this price point, would have preferred a 10-year lithium backup battery in place of a 9-volt. Bottom line: This is the second unit of this type I've owned, the first reaching end of life after 10 years (CO alarms wear out eventually) and cheeping nonstop to announce same. I tested this one, briefly, with my lawn mower running in a closed garage (with me outside a cracked side door, just in case.) It did indeed start reporting CO levels at around 40 ppm, which steadily climbed until the alarm sounded at about 100 ppm. (Whereupon I held my breath, quickly went in, shut down the mower, opened the big door, went back out and waited until the CO level became too low to measure.) The only additional function I wish it had is a remote link, wifi or whatever, to notify me when I'm unable to hear the alarm. No complaints otherwise. Five stars.

Great product and easy installation process. Sits near my kitchen area but far away enough to detect smoke.

For me, trust is the most important issue with a gas detector because I'm not going to be testing them by running gas for the test. So I'm going with what I think is the most reputable brand. I have 3 of these, one for each place in the house where there are gas appliances - kitchen, laundry, and utility rooms. I know the warranty and expiration date are headaches but there doesn't seem to be an alternative to that anyway. The sensors don't last forever, at at certain point you have to say enough is enough and that sensor contamination buildup (or other sensor aging issues) means you don't want to be relying on it after around 5 years. I figure if I get 5 years of use out of it, I got my money's worth, and if it's a year or two longer, sure why not. Unfortunately I don't see any gas detectors for penny pinchers anyway - I should know, I'm a penny pincher myself. But safety first, please. Some things like safety and fire prevention really are more important than low price. One point off for Kidde making the expiration date invisible until you open the package. Obnoxious. Maybe they have some good reason I don't know about.

This was an order for a replacement product as our previous same model product had reached the end of its 7 yr. life. I was pleased that Amazon carried this same product as Home Depot no longer carries it. The product was delivered two business days earlier than expected and that was a nice surprise.

I typically buy the two primary brands of CO, smoke, etc., detectors. Kidde is one of them. I have Kidde products in multiple locations and multiple styles / use cases. We recently had an experience with CO in one of our locations. These specific detectors signaled properly and accurately, i.e., they did what you want them to do. The readout with the max measured ppm feature is also good / helpful. The deign in general is also good -- occupies potentially one of your two positions in a standard US NEMA outlet and the read-out hangs in the right direction rather than at a strange angle. I would buy these again (and have done so).
