Review on WahooArt Ultrasonic Electronic Repellent Cockroaches by Dan Santos

I live in a tiny 700 square meter apartment. Feet in an old building taken over by mice after digging up a nearby street. We hear a lot of mice every night and I had to buy dozens of jars to put our food in or they would eat it. They even dug into a bag of dog food. The traps we use almost never catch one. I've even made poison out of peanut butter and baking soda and they ate it all, but I don't see less of them. I chose this device based on the positive reviews. Since my apartment is so small, I expected 3 devices connected 24/7 would do the trick. But if anything, the mice seem to be more active. Some reviewers said the mice took days to get away, but I've now plugged them in for a full week and nothing. Also, I would connect 4, but the 4th doesn't work. Unfortunately, the search for a way to get rid of them continues. I am extremely disappointed.
