Title: Useless item
Review: This product does not work at all. It's like a plastic toy you'd find at the bottom of a Crackerjack box. I would suggest doing research on other sonic-control devices (which will certainly cost more), and also to keep in mind that, overall, sonic control devices don't have a great track record when it comes to long-term effectiveness.
