Has anyone tried a motion detector water sprayer?

They are particularly nice on hot days when you forget that they are on.
The spray pattern can be set and there is an sensitivity (low to high)
knob that allows you to turn it off when you work in the area. The
"Hounds from Hell" no longer dig in my lettuce patch (Who keeps barking
when the day is done? Who digs up the garden just for fun? psycho-dogs,
psycho-dogs.) and our pride of cats have had to find another toilet with
harder ground.
