It’s very easy for use, just plug in .. after use this , my roommate and I both feel the fly is not coming to our room as usual.. we are delighted for us product, we don’t need to always turn off the light just because we want to avoiding the fly get in our room .. highly recommended!

Started having a spider problem as the weather got warmer and these spiders were not respectful of my personal space. Wanted a quick fix that would be as unobtrusive as possible and not harmful to the air quality.Plugged these in as soon as received and have not seen a spider since. One in the living room, one right by my bed.The light is a bit bright on the one near my bed, the socket sits near to my head and almost serves light a night light. If the brightness might bother you when you’re sleeping then consider positioning the plug in somewhere else.Happy with the purchase, would buy again.

Definitely not working. I have been wanting to leave a review for quite a long time and i finally managed to find the time. This machine is not doing anything for the bugs to be distributed. I wanted for my child's bedroom to make sure there is no spiders or other bugs entering but i saw a spider right next to it it wasnt bother at all. Not to metion the mosquitos and the flies. I definitely think its a waste of money. No recommendation from me.

Seems to have reduced the number of spiders however I found a spider right next to it on the counter and one by the fridge near the plug in. Dont expect a miracle

Well, no more ants! Without powders and ugly traps that I would have to guard against a dog and a 3 years old kid. And unlike other devices I've seen in action, I actually don't hear them. I know, most people say these things can't be heard by human ears. But my ears seem to be different and I can usually hear the noise that pet and pest repellent devices make. And it is quite bothering. This time is quiet for me too and that is very good. As long as also the bugs and the ants stay away... It's more than perfect.

I feel that it has helped to keep the bugs away in the garage. At first, I was a little unsure that it would work, because this repellent don't make any noise at all. Works like a charm, Haven't seen a spider for months!

We have rats in the walls of the house because we live next door to a food place.I've had these plugged in for about a week now (plugged into the wall where we hear the rats) and it's made no difference what so ever.Also we get a lot of spiders in the downstairs toilet for some reason and they're still hanging out as if nothing's bothering them.Bit of a waste of money I'm afraid...

I've only had these for just over 5 weeks so I may add to my review later down the line. But I usually get spiders coming into the house when it's raining or has been raining, anyway I usually see two or three spiders a week strutting their stuff across my carpets, but since having these plugged in I've not had any spiders crawling around my house, I've seen one but he came up through the bath plug hole into the bath. But in the two rooms where I've got these devices plugged in I've not seen any spiders. It doesn't seem to deter flies though. But they don't bother me as much as the spiders.
