Not seeing any difference

I've used these sort of devices for years and they just work.It can take a couple of weeks though,because rats are smart enough to try and turn them off,you may see scratch marks where they've tried to bite through them.When they realise they can't,thats when they move out.Rats like to have a good sleep and they can't stand the noise that comes from them'if you place your ear close,you can just about hear the click,but to a rat its like cymbals clashing.Also thy are thin enough not to stop other plugs being plugged in next to them.

I have a variety of spiders coming in my home and thought i needed new ones, as the ones i had were quite a few years old but after purchasing these, they have made little to no difference.

The mousse was laughing at me. Did not work at all

Light on devices has stopped coming on presumably item is dead. Didn't notice a difference in the few months of having the item switched on. Wouldn't buy again. Didn't even work for spiders and fly doubt it works for rats and mice.

I have had these plugged in for weeks and still have loads of flies

Easy to install, you just plug in to a socket and forget it, after 2 months the rodents are still here so I'd give it a zero for effectiveness

These plug in pest repellents are brilliant; we use them indoors all year around. Some people I know assume that you only need to use them if you get rodents in the house, or in the summer for flies etc. Well the reason I use them is to keep my house bug free, whatever the season; they can clear spiders, houseflies, and other creepy crawlies who are looking for a home in the winter months. Yes, if my cat decides to bring a small rodent into the house, always live ones! they are also very good at getting rid of them too.Now I have just mentioned I have a pet cat; and unlike the repellents used in the garden, these indoor ones only emit a lot lower sound, so only small insects and creatures can hear the Ultra-sonic sound. As I can't hear the sound, you might wonder how I know they work; well the answer is, I don't have any creepy crawlies in the house, because I have one plugged in, in every room.Simple to use, plug in, they light up to show they are working, and within a few days any insects, or small animals will be escaping, as they high pitched sound drives them away.We also have one in the garage; you do need a mains point to use them however; and yes I have checked, the devices use such a small amount of energy, it doesn't even register on the meter.A good value set, clean looking design, well worth getting.
