I got one from ace, and its range in my house is about 20 feet.
Nothing gets through my house well.
Plaster walls, 16 inch joists, concrete brick filled with cement.
It was built in 1928, when this neighborhood was where the rich
professionals built their houses.
Nothing gets through it.

I got one from Walmart last week for $12.97. Its actual range seems to be
about 80ft.
