Review on Ultrasonic Pest Repeller Plug Electronic Household Supplies for Indoor Insect & Pest Control by Jeremy Therrien

First let me update my experience on this item as this is my first time buying two of these items. I didn't see any improvement. I was still seeing mice now that I've had these things for over a month I haven't seen any mice so let me just say I don't know if these things caused the mice to come out of hiding and that could explain why i saw that many in the beginning and thought something was not working, i will say that you need some time not to see any sign of mice so i decided to update my experience, them work, it's just a slow process for them to get started
