At least one lister has reported hearing that they work and having
good results with one. However:

I am extremely skeptical that (1) a _passive_ device so physically
small in comparison to the target meant to be concealed can make
any difference and (2) that a _passive_ electronic circuit exists which
is efficient enough to perform the noise mixing and re-transmission
functions claimed in any useful way.  This has "snake oil" written
all over it IMHO and you don't have to go back into the archives
too many months to find a reasonable thread on it.

If  anyone finds the C&D&R&T report that Mike mentions, they will
find plenty of skepticism there too if memory serves.
