I have found success with this. You used to be able to hear it running along the floorboards up and down the hall at night but since using this there has been no sign of it whatsoever.
We put these all over the house when we had a mouse problem, didn't work that winter but did stop them coming back the following year... Glue traps, never again... Grim...
Maybe ours just has sensitive ears.
Which setting did you have yours on? I put it on the lower frequency. At first I found it annoying as I could just about hear it but quite quickly I forget it was there.
