Ultrasonic Repellent for Rodents, Insects, Indoor Electronic Insect Repellent & Mosquito Repellent Ultrasonic Anti Cockroaches, Flies, Mosquitoes, Cockroaches, Ants, Spiders, Fleas (Set of 4)

This product is completely ineffective so much so that the mouse in my kitchen has been joined by a friend and the two of them are brazenly running about. Thanks for the request for feedback Amazon ... it’s a reminder for me to return the product. It does not do what it says on the tin.

I liked them because they were a handy size but only two of the four items are working. Waited almost a month for delivery. Not worth the money.

Didn`t put off the mice in my workshop.

Excellent product
