I don’t. I remember they were not expensive. What finally worked for us was we figured out where the mice were getting in and we sealed it up.
The sonic repellers I bought were small plug in things, and I had plugged one of them in the correct room where the mice were getting in, but it was about 12 feet from where they came in. Possibly, if it had been closer it would have worked better? I am just guessing.
If I remember correctly, I had purchased three total. One in the family room (where the mice happen to be getting in) one in my bedroom, and one near the garage. I figured I didn’t want to wake up to a mouse, but I have never seen a mouse in my bedroom anyway. We actually almost always saw a mouse in the room where they were coming in. I don’t know mouse behavior, but maybe they tend to stay close to their own homes and where you find them might be a clue. Again, I am just guessing.
I also wanted to mention that at first I called a pest control person, and they priced sealing up my house for over a thousand dollars, and I feel pretty sure he would not have found or sealed where the mice were getting in my house. We wound up paying a handyman $125 when we figured out where they came in, which was through a space in the fireplace.
