Query: Chime with a mind of its own

This is a product that works fine for its purpose and then also works when it wants to on its own. When I read on other reviews that the chime started to ring on its own, I assumed that they simply didn't replace the batteries on a timely basis. However, my new chime started spontaneously and magically ringing on its own during the first week I had it in place by the door. I put it on my dresser, and now every once in a while for no apparent reason it chimes. I plan to return it. Who wants a doorbell in the house that rings when the dog isn't anywhere near the door?
