It’s very simple to use, and harmless to children and pets. Best of all, it’s effective! My other unit (a different brand) makes an audible, high pitched whine. This one makes no sound at all.
It’s been plugged in for about three weeks now, and I don’t hear or see any evidence of mice now. I plan to buy one for each room of the house, and I’m recommending them to everybody.
If you’d like to grab one, you can find it here. I received this product at a discounted rate in exchange for my honest review. The opinions expressed are 100% my own.
