40 Winks Ultrasonic Pest Repeller Mouse & Rat Control - Remove Mouse, Flies, Wasps, Ants, Spiders, Bed Bugs, Fleas, Roaches, Rats, Mosquito repellent (2 Pack, UK plug)

The media could not be loaded.  Have had problems with spiders and flies in my house for ages, tried all chemicals targeted at removing them, as I'm asthmatic this was not a long term solution. Tried 40 winks ultrasonic pest repeller, within days all the flies and spiders had disappeared. Would definitely recommend this product.

Works well in bedroom even below the recommended height above the floor as sockets are generally not at this height.

I've been holding off writing this review as I've seen different people have had different experiences as time passed.  However, I've now had these running for over a month and have had a great experience.My problem - mice / rats maybe - in an outside wall.  These little sods were driving me mad as I work from home and every single day I could hear them scurrying around in the wall behind me.  Their party-trick was to run along the steel lintel above my office window which made it sound like a herd of elephants (with scratchy toes) were inside the wall.From the moment I plugged these devices in (one in the office under the window and one in the kitchen below) I've heard nothing at all.  For me it was an instant fix and has been the case ever since.Very impressed - long may it last!For those interested in power usage, I checked with a power meter and each unit uses 0.6 Watts.

I have been tormented by the prospect of mice in my kitchen at night. I had accidentally left out burger buns and found most of them eaten. This was terrifying as I have never seen anything like it before. My neighbor advised me that it might be mice. I then bought traps (and stopped leaving food out, yikes!) but these did not work. I actually thought that maybe it was just a once-off until I went to my kitchen late one night and met the mouse physically (eeekk!!) I could not find an opening for the life of me so I bought a camera to see if I could see where the mouse was coming from and set up traps once more. I literally watched the pesky little mouse skillfully avoiding the traps and going about its business in my kitchen. Finally, I bought these and there were no mice since day one. I have had them only for two days (one in the kitchen and the other in the living room) at the time of this review and both nights, there was no nocturnal visitor. I am relieved, but also aware that it is pretty early to make a final conclusion and as such will monitor a couple of more weeks and edit if need be.Edit: I am dismayed to note that I reviewed this product too early. The mouse is back, even crawling nonchalantly in close proximity to the device. Perhaps it will take effect after a few weeks as the package says 😢

I think they are working. No real way to measure their usefulness.

Doesn't do what written on the box

Nice little light and slim perfect

I am happy with this product.So far I found 3 cockroaches laying on the floor of the office not dead but unconscious (the moment I grab them with paper they move, gosh😱) 2 on the same day, and another 3 days later. So it’s all good.Will order more for the all house!Happy, happy
