MERRYL Ultrasonic Pest Repeller - 2 Pack, Black

Bought as a humane way to get rid of a mouse that I hadn’t actually seen just seen droppings.Since I’ve been using these there seem to be more droppings and I’ve just seen the mouse .... running directly towards where one of these is plugged in. Definite waste of money.

I can't say these made a difference as the cats are still finding mice (house cats)Can't recommend personally, buy can't say they won't work for you - I have an old house with thick walls so maybe that stops them being effective

Plugged them in and the mouse was gone. Didn't quite believe it but within a few days it seems to have done the job. Easy to fit and relatively inexpensive. Worked for me!

Light is ok serves as a night light in kitchen but is annoying in bedroom as bright. Took a few weeks for scratching noise to go so assumed the device worked.

Why did we not know about this before?!Living in country, we always have mice problem-& this will save us an absolute fortune

The top plug prong (earth) came out the first time we used it. Cannot comment as to it effectiveness of I can't plug it in safely.

Absolutely Useless!Found a mouse in my porch, I’m loathed to use poisons so opted to try these. My porch is only small so should be easily covered by the sound waves produced.Actually found said mouse sat on top of the device.... do NOT waste your money.

Easy to install, still have a few mice, but not as many.
