Great for camper/rv
Bought this for the camper. Easy to setup. Can be mounted. Very loud during the testing. Seems well made and very light weight. Gave us peace of mind while camping.

Simple, Reliable CO Alarm for Peace of Mind
Simple, Reliable CO Alarm for Peace of Mind The Kidde battery-powered carbon monoxide detector is an easy and affordable way to add an extra layer of safety at home. I like that it runs on batteries, which makes it portable and flexible—you can mount it on a wall or just place it on a shelf without worrying about wiring. The test/reset button is straightforward, and the LED indicators give quick reassurance that it’s working. It’s very lightweight but still feels solidly built, and installation was as simple as popping in the batteries. The low battery chirp is loud enough to notice, and the alarm itself is piercing, which is exactly what you want if it ever goes off in an emergency. Because it’s battery-powered, you’ll need to stay on top of changing batteries regularly, but the trade-off is portability—you can move it between rooms or even take it on trips. For long-term setups, combining it with a hardwired or plug-in unit gives the best coverage. Bottom line: A dependable, no-frills carbon monoxide alarm that’s easy to install and portable—an inexpensive safety essential for any home.

J'ai acheté ce modèle il y a 10 ans et c'est le terme de ce produit, alors comme les 10 ans étaient terminées, j'en ai acheté un autre identique car j'étais très satisfaite de ce modèle. Merci
