  • The alarm for fuel heat homes.
Color: 1 piece
Peace of mind seems to be well made. Definitely has a “catch your attention” sounding alarm. This would save a life. No question worth the cost.

  • Easy to mount, and takes up little space
Color: 2 piece
I can't say how well they work because we haven't needed them and hope we never do! But, I can say they look good, they are small and very easy to mount on the wall (either with the included screws or adhesive mounts also included) and the instruction manual is very informative.
