What Others Say
Very good product
I bought this over two years ago and it is still working fine.
Easy to use. I tested it several times and the sensors each time worked. And the alarm sound is pretty loud as well.
We now feel much safer when sleeping, knowing that the alarm would alert us if anyone is down stairs.
