Keith, No experience with it or direct knowledge. However there is no such thing as a "force field" and I seriously doubt any such gizmo could place a very large high frequency magnetic or electric field around the wiring of the entire house.
It's just possible I suppose tha radio freuency energy at some particular frequency might disturb rodents, but I suspect if it worked everybody would be using it. If they offer a no conditions no questions money back guarantee over longer than a month, then maybe it'd be worth a try, if you can really find a way to be sure it worked. QVC's reputation is, well not great. I'd invest in some boxes of bait and put them where other pets can't get at them. That will work, although you may have some smells for a while. tom Fowle
