Great little addition for peace of mind.
Had these on about a year now and really impressed, they are SO loud! We use them on our front and back door for extra peace of mind. Easy enough to put on and they've stayed on for a year and still going strong. Really impressed and definitely recommend for extra precaution, especailly becasue we have pets so we can't turn our alarm on at night so this is just nice to have and we know it will wake us up!

Loud and ideal
These came in perfect for what I needed them for. You do how ever need to check the batteries every now and again to make sure they are still working. Came with its own fob to activate and deactivate
