Siterwell AA Battery Operated Carbon Monoxide Detector Alarm, LCD Display,Portable for Travel Home,1-pack

Seem good. Everything works as described in description. Shipped fast and does the job. I have only had for few months, so will see if battery will last and product will hold up over time.

Easy to use/set up. The ability to put this on nightstands or other places besides a wall is very convenient. It also has a stylish non bulky look.

Was as described and easy to use.

Very pleased with this product!

After hearing about the death of a young man in a resort hotel room I bought this for travel. Put in the battery and set it in hotel room instead of relying on hotel maintenance. I never fly so I don't know if it would be allowed on board?

Description indicates a Product Life of 10 years. The item I received is labeled with a product life of 7 years. Hard to fairly compare items and price when the description doesn't match what you are buying. For another 3 years of product life I would have bought the kidde brand, my last ones actually lasted 10 years

Having an unvented propane heater, I wanted to monitor that it was not putting out any carbon monoxide. This unit is better than others because it gives you the actual percentage perceived in the air and not just a dummy light red or green. It is definitely worth the extra $2. Over the cheaper models

the package was a used or prior returned item the tape strip had finger prints one side, cut tape on the other side. never unboxed them plus arrived two days late.

Wanted peace of mind so I ordered one. It does not register any Carbon Monoxide even when placed next to my propane camp stove and while using my propane heater. I can hold it around and above the two and it reads 0. Now I am more worried about my safety, along with everyone else's. This item should not be sold.

I just got this and was getting ready to hang it on the wall but they did not include the screws or plastic stoppers as they call them that are needed to hang it on the wall. They are clearly mentioned in the directions that they were included but they were not. That is why I gave it a 1 star rating. I have no idea how well this CO alarm actually works but that was a bad start for me when the company does not include everything needed for this product.
