Ultrasonic Pest Repeller,Goalwoo Electronic Insects Repellent Rats, 4 Pack

They seem to work well, no problem with flies, mossies, midges during this hot weather, quite surprised actually.

This product has been a total waste of money. I have given it more than the 2 weeks that its supposed to take to work and it hasn't made the least bit of difference. Does not work!!! Had to give it a 1 star rating to be able to post this but it isn't even worth that

Seem to be helping. The magnets come with the product are pointless but didn't pay extra for them so that's okay. 1 of the plugs lasted around 2 minutes before broke but the other 3 are working as the blue light stays on. Came well packed and with good time.

Fab repelled any insects over the summer!

Purchased at the end of July and one unit has already stopped working!! Blue light gone off so presumed unit has died.

works perfectly for now well worth the money

I bought a pack of 4 of these electronic devices and it has not made the slightest bit of difference still get all the flys n mozies in doors.

Could live with without these,hate spiders!!
