The Big CheeseSonic Mouse & Rat Repeller Plug-In, Humane, Ultrasonic Rodent Pest Deterrent for the Home, Safe for Use Around Cats and Dogs

significantly reduce the sign of mice from my house. Purchased this item on Oct 2018 but I am still using in 2024. Back then I paid less then £20 that was value for money

Please don't waste your money on this, it doesn't work the past just come and go as if it's not there might as well be a bit off meat

I expected this device to be much more subtle than it actually is. it is able to be heard around the house by human ears and has become an annoyance for me and my other half, I emailed the seller about the noise and their response was simply yeah. it's noisey

Helped in me getting rid of some unwelcome guests in my home

Used to think product was great but saw a mouse recently when we had started to use it again, however have not seen it since

Haven't seen any pests since turned on

Bought this for my mum as she gets mice in her loft - still waiting for it to work but it's only been in for about 3 weeks now, hence the average value for money as I'm still not sure yet.

I installed one of these on each floor of my house including the loft. Although it states safe for household pets, it’s important to add that this is dog, cats, birds and fish and not anything small and furry or rabbits.I can hear one of the repellers, it’s a high pitch whine when I move around the kitchen, so it’s working but a little bit annoying.A few weeks after installing a mouse was in my conservatory but it was not in a good way, and seemed dazed which may have been due to these units.I haven’t (fingers crossed) seen anymore signs of activity since installation but I have also filled any visible gaps with wire wool and silicone sealant to act as a deterrent too so it’s hard to say what’s effective but as a peace of mind I will keep these running
