The Big CheeseUltra Power Mega-Sonic® Twin-Speaker Pest Repeller, Repels Mice and Rats, Whole Room Protection, Double Speakers, Powerful, Electronic

Great product. Got rid of a load of rats in my barn. Does a large area. So good I bought a second one.

A neat, powerful and versatile unit with a convenient test button that drops the tone briefly to human audibility. I can't definitively prove it has worked (as wild rodents are notoriously hard to catch and track), but we've certainly seen no mouse activity in the attic since installing.

Exactly as described

Nice one

Having got this there have been no signs of mice in the house.This may well be a coincidence and the mice may have relocated of their own free will. I like to think it is down to The Big Cheese though..

Put 3 mouse traps less than a metre away from the speaker and caught 3 mice in one night. Not much of a deterrent ☹️

Nearly full success but still waiting and hoping. We're a good few weeks on. At first despite this being plugged in and making a noise mouse are meant to hate, the Mighty Mouse that defies all attempts to get rid of it still pottered about in front of me, laughing in the face of traps, humane or otherwise, and the sound did not seem to be disturbing it. I was annoyed as I have spent a fortune on the recommendations which never work. However, it seems over time to be working. Used to be sighted daily, now not seen for a fortnight, but I hear the odd scuffle. It seemed it wasnt living here anyway but passing through for a taste of my especially worthy wholefood crumbs. Fingers crossed the noise has now become for him just too much. Like when you get to that point of moving house as the neighbours music is just not going away. I am not 100% convinced he will stay away but it is better than anything else.

Seems to work.

los pequeños roedores se han marchado, asi que quiero creer que el aparato funciona de verdad. Es completamente inaudible, excepto cuando pulsas el botón de test que hace un ruido ensordecedor para salir corriendo.
