Negative Positive
Title: Completely useless and ineffective
Review: This product is a waste of money. The mice in my room are completely unaffected, and walk right by the device without any sign of concern. Besides being ineffective, the devices themselves make a slight buzzing sound (not silent as advertised). I now have to buy a set of (humane) mousetraps, and I recommend that anyone reading this do the same and save themselves $40.
