Seems like a good idea if the washing machine hose breaks in the basement,
or the water heater starts leaking, I would think.

Do they work (well) ?

As long as the battery is good-

Any particular brand you folks would recommend ?

For a lot less than $10 you can build an alarm that will be louder,
simpler, and more flexible than the commercial version.

Go to radio shack- pick an alarm [there are several choices of sounds-
just get a loud one], some wire, and a 9v battery terminal.

Wire up the alarm so it is always on- snip one wire - strip ends.
Glue ends onto a little piece of non-conductor [wood, cardboard. . .]
about 1/8"apart. Lay on floor with contacts down. When wetness
occurs it will compete the circuit & sound the alarm.

Any caveats in their usage, etc. ?

Thanks,
