The blue light is unobtrusive - yet to be seen if they work. I was attracted by the previous reviews.

Unwanted critters in the house are always a bit of a nightmare. This is the first time I have tried an ultrasonic device to see if there was any noticeable difference.The device seems to be quiet enough, I can’t hear anything, and my cat doesn’t seem to be annoyed by it at all. The device itself is very much just plug and play, and very much hassle-free.Since plugging it in, I have noticed there is a notable reduction in the number of critters seen. There are fewer spider sightings and less fruit flies hanging around. The unit is discreet and I appreciate the fact there is no upkeep or anything to refill.★★★★☆ - Good

They are quiet and discreet easy to use I am very pleased with this product

Having struggled with unwanted critters in my home, I decided to try an ultrasonic device to see if it could make a difference. After plugging it in, I noticed a significant reduction in pests within a week. The device operates quietly, and I appreciate that it's non-intrusive in my living space. It's reassuring to know that it's safe for both humans and pets; my dog seems completely unbothered by it. The simplicity of just plugging it in and letting it do its job is a major plus for me. It's been a hassle-free solution that has made my home more comfortable.I live in an area where insects and small rodents can be quite a nuisance, especially during certain seasons. Traditional methods didn't seem to work effectively, and I was reluctant to use chemical solutions due to health concerns. Since installing this device, the usual signs of pests have diminished considerably. There are fewer spiders in the corners, and I haven't seen any mice activity in the kitchen. The device is discreet, and its coverage seems sufficient for my flat. I also appreciate that there's no need for maintenance or refills, which makes it a convenient option for someone with a busy schedule. It has provided peace of mind and improved the comfort of my home without any fuss.

Generous 4 units. Had them for more then 2 weeks before reviewing. Easy to install. Just plug them into the socket and a light blue light is lit.I installed 2 units in my kitchen. Has it helped? Errr... in some way. The flies still come but they are slower, so maybe these units emit bionic waves that make them into zombie like state. So now you can now swat them easily with great "satisfaction". No more "chasing". Happy days. Get them if you want to get some satisfaction in fly swatting.

Well plug is British so the owner of the company must know it will be used in Britain. plugs here are literally at the bottom of the room usually but then product required to be between 2-6 feet high, but not covered with anything in any directions. How does one manage to achieve that in the UK? Anyway, it is plugged in for 23 days now, mice are still thriving but at least when they are not, I can still not sleep because this product lightes up the whole room. Highly recommend for someone who doesn’t like to be in the dark. Natascha Kampusch can you read this?

The ultrasonic pest repeller has been doing a solid job at keeping unwanted pests out of the flat. Plugging it in was simple, and after a few days, I noticed fewer insects around. The best part is that it’s not invasive at all — I don’t hear it, and my cat doesn’t seem bothered. I was a bit unsure at first, but it’s proven to be effective without needing any sprays or traps. If you're looking for a quiet solution to deal with pests, this does the job well enough.

Appears to be a bit plasticky but only time will take if they do the job
