Query: BOB IN FL

We have been having some water issues in the condo building so I purchased this to put by the water heater. I tested it before I put it on the floor. Perfect. The next day, I went to demo this for a neighbor. Didn't work. Changed the battery, even though it was new out of the pack. Barely a click. Wouldn't wake the mouse. As others have said, great idea, VERY POOR quality. Took it apart and put another new battery in and still just a clicking sound. Others have had the same experience. Amazon needs to pull this product and get our money back from Sonin.
