The sensors were easy to install and testing has so far been successful. Hopefully we will get 10 years service from them.

It is neat and was easy to install. It is a replacement for a similar device of the same make (Kidde). My only concern is that the previous device was very sensitive and would go off if, say, the toast burnt. This one does not respond and yet it is positioned in the same place.
