Ultrasonic Pest Repellent,ultrasonic mosquito repeller,ultrasonic trap for mice and rat-High Power With 3-in-1 Frequency Conversion Repels Away Insect,Flea,Fly,Spider,Roach,Dog,Rodent,Bugs,Ant-4 Pack

Installed these when I received them and so far no sign of any spiders! which was why I bought them, so seem to be working (fingers crossed)Item arrived promptly and transaction was nice and smooth

Had them a couple of months and 2 have packed up. When I say packed up I mean the blue LED has gone out on 2 of them so I assume they are not working. I have no way of knowing if the units with the LEDs un-lit are giving out the high frequency as last time I looked I am not a mouse.Don't waste yer money, buy a trap.

Since I plug this device which is almost 2 weeks, I did not notice that this devise working to keep the mosquito, flies, spider etc. away. infect flies and spiders are enjoying near the device. :-)For me, this device did not work as describes.Kind regards,Qasim

One stopped working after a few days. The light is off.

Seems a good product.

These products were crap didn't do the job at all, still had creepy crawlies come in, wouldn't recommend at all, waste of money

After leaving them plugged in for a few weeks I had to call in an exterminator, they just didn’t get rid of the mice. Not doubting the success others had but they just didn’t do anything for my rodent problem.

Been using two of these in one room for over a month now. Found a spider right next to one and flies etc seem to stop be around. This for not seem to make any difference.
