Guffo Ultrasonic Pest Repeller, Safe and Silent Plug-in Insect Repeller, Electronic Portable Pest Control Repellent Against Mosquito, Cockroach, Mice, Rodents, Spiders, Flies, Ants Pest Reject (2)

To be onest, I didn't expected to work, but guess what? I was wrong. The flies, spider or whatever are gone from my house and I cand have my window wide opened because nothing comes in.

I bought this item a month ago & got up this morning to see 2 spider webs with the spiders in residence in close proximity to it also ants seemed to be totally unbothered by it.Another point is it could double up as a night light, as the blue light is quite bright with no way of turning it off without turning the whole thing off. Which I now have to save electric!

Summer is coming and there will be a lot of mosquitoes，So I bought this stuff.The product is light, and doesn’t consume much power.Really easy to use.Just plug and play function,It seems to have some effect in preventing pests.I'll get a few more for around the house.

I had a ultrasonic spider repeller of another make which unfortunately, after several years of great functioning, stopped working. I was determined to replace it with a new one of the same make but it was out of stock so I decided to browse amazon and see what I could find. I bumped into this one and I decide to give it a try as it had fairly good reviews, it seemed good value for money and it also claimed to works as a repellent against various insects and animals.I've had it now for few months and I can say it's a total waste of money! I had the house full of mosquitoes and flies during summer and now there are spiders in both of the rooms where a plugged in these devices.I don't recommend it.

not sure why but mine has not worked still got flies etc in the room and chose this one as it had good reviews, will not bother with one again

Quick delivery. Not sure how good it is as only had it a few days. But seems to be doing the job.

I bought these as I was sick of the pests in the house.I don’t think that they work at first, but they do. I have noticed less flies than normal so far.The product is small, and doesn’t consume too much power. It is easy to use,just plug it in and turn it on. It has done the job well so far.Great pest repeller !

This pest repellent seems okay. I may have to give it more time. I have had one or two signs of pests since plugged in. However there are fewer signs than before.
