These are so easy to use. Just plug them in! I like that they seem to be keeping spiders out of the house and I don't have to worry about my kids or pets getting into anything dangerous.

I don't like anything about It I just waste my money.

Was good product, but sometimes I still can hear some noise.

"I had a little problem with pests, specially st night. I seen this online somewhere for these ultrasonic repellents and in stores. They all claim to do same thing, so after giving it a few nights to try it out I definitely noticed more th the first night, it did say it would do that. Last night much better. I am not an expert on theses repellents but it seemed to work. Since I don't have a mouse problem, I don't know about that. The extra feature I liked about this was the night night. Just press the lower small button, on it goes."
