Mouse Out Mini-Sonic Repellent – Ultrasonic Pest Repeller – Round-the-Clock Mouse Deterrent that Prevents Return - Rodent Control Product – Mouse Repeller Plug In, Pet Safe – 3 Pack

The mouse left the very next day and didn’t return, small, very easy to set up and use

Absolutely brilliant. Does what it says. Have had no further issues. Continuous use prevents any rats and mice issues.

Didn’t work and only one of them was actually making and sort of signs of noise.Waste of time, ended up sending them back.

I find these work well in the attic but only last 2 months and die. Maybe that is why there are 3 in the pack. Shame as good otherwise. I've already thrown 4 away, they should last longer.

Nobody knows if it works or not, a bit like Schrödinger's cat

That said they work because I've not caught anything yet so

Since using this 3mts +No sign of the mice 🤞

Does the job
