My only concern about this product is that it was manufactured in 2015, and the sensor is only supposed to last for 10 yrs. I just don't know if the time starts from when the batteries are added, and the unit is powered on, or if it starts from 2015. If 2015 is the case, I will only get about 1yr. of use from it, and it will not worth what I paid for it. I am going to be optimistic, and go with, the time starts when the batteries are inserted and the unit is powered on. If that is the case, this was a very good buy.

This is a 5 star product because it lets you know when the battery need changing. It's better than buying a non-talking one which the beeping when the battery is low can be very annoying. I personally feel it gives me peace of mind knowing that it's working.

Simple to install and use. The new and improved design lets you replace the batteries without even taking it down. Good price for dual detection.

The item will detect both smoke and carbon monoxide. I owned on previously and it lasted for almost seven years, I like that it talks to you to tell you what is wrong with it. like low battery or smoke or carbon monoxide.
