USCVIS Ultrasonic, Electronic Pest Plug in, Drive Insect, Mice, Mosquito, Ant, Spiders, Away from Your Home, Bugs Repellent for Indoor Use 6 Pack 【2019 N Sound generators

Firstly, one of the six failed out of the box. That said it may have only been the failure of the light indicator that shows it is powered as you cannot tell if it is actually producing the required high frequency noise that it is supposed to, and could be why there doesn’t seem to be any reduction in the flies, wasps, spiders etc. This makes it difficult to assess whether these are working or not. If the light is on and assumed working, it certainly doesn’t deter anything although we may just have a large number of deaf beasties. As a previous reviewer mentioned, the operating light is bright so if you like a dark bedroom then these will certainly keep you awake but will probably help stop the bugs bashing into the walls and furniture.

Easy to install, just plug in... There is an instruction manual that tells you there is no way of knowing if this item works for 6 weeks, as I've not had any pests apart from wasps and lots of them, but I need to wait 6 weeks before judging, because that's how long the item takes to work!! One plugin lasted less than 2 months and the light does not work so I assume the item doesn't work either. It's too late to return the item so ive wasted my money....To be honest... in hindsight.... I wouldn't waste your money on these if I were you.

Recieved pretty quickly, only put them on today so not sure how effective they are. Only issue about them is its meant to release a sound not heard buy the human ear which is nt true. Every few seconds you can hear it clicking which can be annoying

Having had good results with this type of pest repeller in the past 2 years, I have recently been purchasing some for friends and family before the warmer months set in. With this model there is a blue LED on both sides that light and then fades for around 10 seconds then comes back on again, but apart from that you will not notice anything else happening. I currently use 5 similar devices in the home so this 6 pack seemed like a good purchase but on arrival I found them to feel cheap and somewhat flimsy. In saying that if they do the job then they are great value so I will update my review of these in a few months.

Thought they were great when first plugged in, now not so great doesn’t scare anything. The spiders have moved in AND invited anything else that creeps or crawls to party. So not full proof.

I've used them for a couple of months. They have no effect.They created nice light night though.Time to look of other options.

Would of gave five stars but one of them have stopped working after a week other than that they really do work.

I think mine doesn’t work. I placed a spider on the device and it was just chilling. It didn’t even look bothered.
