Fast shipping. Cheap item from China. Hopefully this works. Very flimsy mounting plate that breaks really easily. I will not purchase this item again, I would opt for a more expensive more robust item next time.

Like: Light, Easy to use, Power by 3x AA battery (vs the more expensive & less commonly use 9V battery).Dislike: None at the moment ... But sure is a concern because most CO monitor I bought in the past expired after 3~5 years. This one has no expiry date.

This particular battery powered CO alarm failed to go off in levels 7 times the fatal level and caused me illness requiring ongoing medical care. The batteries I purchased were the best of the best and I tested the unit before trusting it. Get a hard wired one instead because the fire department told me that these portable ones fail frequently. If you don't have 110 volts, buy an RV rated 12 volt unit and don't mess with this kind. All brands of these little ones have issues, according to the ER doctors and fire department

Purchased two of these for my split level home. Very easy to install. They are a perfect size and not too large so they do not stand out. Functions as expected. No noise. A good value for the money. I will be purchasing more of these to add to different rooms in my home.
