Do the plug in repellers work?

For repelling Elephants yes . We plugged one in about a six months ago
(didn't buy it MiL went into a home so we 'inherited' it) since that
time we have had zero elephants in the living room, proof positive that
it works as an Elephant repeller, but as for Mice it probably doesn't
work (but we haven't seen any mice either).
Being rural we used to get field mice a lot but this time of year they
seem to prefer all the fresh fruit and Berries and all the fresh air,(
may well be a different story come winter).
